This Might be the last chapter that I write in a single day since I have a few more things planned for Chapter 4.

Hope you enjoy.


"Ruby Hoshino…Or rather…Sarina Tendouji…I want you to be my girlfriend." Ruby's eyes went wide as she stared directly into Aqua's eyes, her tomato red face threatening to only get darker as she looked towards the side, her heart pounding against her chest as Aqua held her close to his chest.

After a few seconds of silence, Ruby briefly turned her head back and gave a small nod. "...O-Ok…"

"I take that as you accepting?" Aqua spoke in an almost joking tone as he forced a smile onto his face, as Ruby pouted some as she buried her head into his chest suddenly.

"Geez, what else would it mean…?" Aqua kept his forced smile as he pulled Ruby fully into a hug, patting her back with his hand as the darkness in his eye briefly glimmered some.

"We can't tell anybody, not even Miyako, Kana or Mem, alright? Not only are you an idol and I'm an actor, but us being siblings makes the matter even worse to the general public." Ruby didn't immediately respond, simply allowing herself to rest in his care before she gave a small nod.

"I-I know…B-But it's not so much different from our past lives, right? Afterall as your former patient, I'm sure people would have raised issues with us dating then."

Aqua wanted to respond back that if she was still twelve years old when they started dating in their past lives, they would have had more issues than just a doctor and patient thing, but he held his tongue and just nodded. "Yeah, in a way I guess…Though, we're not completely alone in this. The director knows and he seems willing to help us out."

"The director…? Hm, I guess you being his understudy for so many years paid off…" Ruby gently pushed herself off of Aqua's chest, looking up into his eyes as she licked her almost dry lips. "But…What about Akane?"

"What about her?" Aqua said with the darkness in his eye shining forth some more as Ruby kept her stare.

"Well, aren't you two dating…?"

"That's nothing more than a work relationship, I have no intention of going serious with her. Actually, recently I've thought about breaking it off anyway…We've been together for a few months now, so most of the public has already moved on from that stupid reality show. Although…" Aqua's dark eye only grew, as images of Ai rushed through his mind, along with the potential knowledge that Akane held.

"Although…?" Ruby tilted her head, as Aqua looked away from her gaze as he spat out his words.

"...Although…I want to remain friends with her…" Aqua gave a quick lie, as Ruby seemed to believe it as she looked down.

"Oh…I mean, that makes sense I guess. Afterall, you saved her from that bridge, and you've been hanging out alot doing that Tokyo Blade play…Speaking of, don't you have another rehearsal tomorrow?"

"From about Noon to four o clock, yeah. I think that's around the same time you and the girls had an idol shoot right? Modeling for some magazine?"

"Well I wouldn't call it modeling, we're just taking pictures in our idol outfits for some small tabloid about underground idol groups so other idols will be present. B-But…" Ruby's words seemed to catch themselves in her throat, as she kept looking back up at Aqua and then away. "I-I can skip it to come to your rehearsal, if you want."

"Hm? Why would you do that? You've been talking about this shoot for a few weeks now, so you shouldn't back out. Kana has already informed the director she won't be at the rehearsal because of your shoot, so you would be leaving her in a tight spot."

"But…" Ruby laid her head back on Aqua's chest, her blush still fully present as she closed her eyes. "I-I want to spend time with you…"

"..." Aqua didn't say anything, his eyes going back to a neutral blank as he looked up at his ceiling. "I see…"

"S-Sorry, I know it's selfish…B-But…I-I've never had a boyfriend before…" Ruby spoke with embarrassment in her voice, keeping her eyes closed as she stayed laying against Aqua's chest.

Pulling his gaze down from the rooftop and looking down at Ruby, Aqua concealed a sigh as he raised a hand and placed it atop her blond head and began to pet her. "In that case…I'll come to your modeling shoot."

"H-Huh? But-"

"It's not a big deal, as I said, Kana is already skipping tomorrow anyway. Other actors and actresses skip all the time anyway, to the point that the dress rehearsal will be just the second time that the entire cast is together. I'll just text the producer that something came up and I won't be able to attend."

Ruby was silent for a moment, guilt tugging at her heartstrings at knowing Aqua would miss an entire practice just to come and be with her.

But at the same time…It made her beyond happy also…

"...Ok…T-Thank you, sensei…"

"...Call me Aqua…I'm no longer a doctor after all, I'm just a lowly actor who is known to high school girls and older moms because of a reality tv show."

"But…Sensei is kinda like a pet name, right?"

"Pet name?"

"Yeah, you know…Couples will call each other cute stuff and um…" Ruby turned her face fully back into Aqua's chest to hide her embarrassment, as Aqua raised an eyebrow before giving a sigh through his nose.

Though he certainly got around and had his fun in his past life, he never had an official girlfriend or anything of the sort. The most he ever had was a few friends with benefits in his college days, and those ended almost as quickly as they began.

So Aqua wasn't exactly in the know when it came to couple stuff either.

Still, as the more mature one, he figured it was up to him to take the lead when he could.

Keeping his hand on Ruby's head as he petted her, Aqua decided to run with that lead. "In that case, can I call you…My Star?"

"H-Huh?" Ruby raised her head off of Aqua's chest and looked him in the eyes. "M-My Star?"

"Yeah, you're an idol and you're going to be the star right? But no matter how popular you get, you will always be My Star and nobody else's." It took a moment for Ruby to realize what Aqua was saying, but as soon as she did, her face only darkened red even more as she went right back to burying her face in his chest.

"Geez Sensei…" Aqua gave a small chuckle, holding her close and petting her as the two of them stayed like that for almost a full minute, not saying anything. Finally, Ruby broke the ice. "I…Love you, sensei…"

Aqua moved his eyes down and looked at Ruby, before halfway closing them as he looked away. "I…"

"No, don't…" Ruby pushed herself off once again as she raised a hand and placed a finger onto his lips. "I…I Know you don't love me yet, atleast….you're unsure. I only want to hear those magical three words from you…When you really mean it, ok?"

Ruby gave a small smile towards him, as Aqua's blank eyes stayed neutral as he nodded. "Alright, deal."

Ruby smiled at him, staying in his embrace as she looked over at the clock hanging on the wall. "It's getting late, huh?"

"Yeah, it is…We probably shouldn't stay together up here much longer, don't want Miyako getting suspicious of what we're doing, especially if she thinks we're fighting again. Besides, you need to sleep early so you can get up and get ready, Kana and Mem will be their early won't they?"

"Yeah, they will, I have my alarm set for eight in the morning…" Ruby said in an almost downtrodden tone as she looked down at the ground. "I want to stay with you longer…"

"Well, we'll have more opportunities, especially since we live together and work at the same agency. Even with others around, we can be near each other and hang out, right?"

"...Yeah, I guess that's true." Though reluctant, Ruby slowly let herself go from Aqua's embrace as she stepped back, looking down at the ground before raising her gaze and giving a smile. "I'm…So glad, I get to be with you again, sensei."

"...Same here, Sarina." Ruby blushed and gave a wide smile as she nodded, slowly turning towards the door and walking over to it as she grabbed the handle and began to twist it.

"Goodnight Sensei…I love you…"

"...Goodnight, My beautiful Star." Ruby blushed at his added compliment, but smiled at him all the same as she opened the door and slowly left the room before she pulled the door back behind her, leaving Aqua all alone.

Once she had left and he heard her footsteps leave, Aqua gave a sigh to himself as he turned towards his PC and walked over towards it and sat down as he ran a hand over his face. "Love, huh? I doubt I'll ever be able to feel that again, but…"

Aqua highlighted Sarina's name on the search bar and deleted it, before typing in 'Ai Hoshino's death' and loading up several articles.

"But even if I can't promise her love, I can promise her that I will avenge our mother." Aqua said with pure darkness in his eye, as the silent moon began to rise over Tokyo in the night.


As the Morning sun hung in the air, Ruby tiredly walked into the Strawberry Productions studios, her eyes bloodshot red from not being able to sleep the night before. Though she laid down in her bed, everytime she even got close to drifting off to sleep, the realization that she and Gouro were now in a relationship came back front and center and made all of her feelings rush back into her.

In total, she maybe got a couple of hours if she was lucky.

As she pushed the door open to the studios, she gave a yawn as she walked in and looked at who else had arrived. "Oh Ruby, morning."

The hot blooded and foul mouthed former child actress Kana Arima looked up from a manga she was reading, as she waved towards the tired idol.

"You look tired, up all night worried about the shoot today?" The older than she looked youtuber Mem-Cho followed up Kana's response with her own, as she had been checking on their youtube page on her phone as she waited.

"Ah…Loli-Senpai…Mem-Chan…Morning…" Ruby gave one more yawn as she closed the door behind her, walking over and falling into a chair as her eyes threatened to close on the spot. "Yeah, I didn't sleep much…"

Ruby forced the words out, as Kana closed her manga and laid to the side as she shook her head. "What have I said about not getting any sleep? It will ruin your complexion and make the next day even worse, especially if you have something for work going on. After our performances recently, I wouldn't think a simple photoshoot would keep you up."

"Mmm Yeah…" Ruby gave another long yawn, her eyes slowly closing as she almost fell into a deep sleep-

Ruby Hoshino…Or rather…Sarina Tendouji…I want you to be my girlfriend.

Once again however, Aqua's words ran through her head as her eyes shot open, her face blushing as she looked towards the side and quickly covered her face with her hands.

Kana simply gave a confused look as she raised an eyebrow, as she reached over to just grab her manga and continue to pass the time.

Mem-Cho however, kept looking at Ruby before a devious smile crossed over her lips. "Ohh? Ruby, is it possible that it wasn't the shoot that kept you up all night?"

Ruby stiffened some as she slowly moved her face over, opening her fingers up as she looked at Mem-Cho while attempting to conceal her blush. "U-Um…I-It was…?"

"Hmmm?" Mem-Cho in the blink of an eye had made her way over to Ruby, her entire expression resembling a devious cat as she poked at Ruby's words. "You never were one to lie Ruby, so when you do lie, you're pretty terrible at it."

Ruby simply turned her face once again and hid it behind her hands, as Kana looked at the entire exchange with confusion as she retreated from picking her manga back up and just looked at Mem-Cho. "If not the performance, then what? Does she have a bad case of diarrhea or something?"

"Tisk tisk tisk, I envy you Kana, to be so young and innocent." Mem-Cho said as she wagged her finger, making Kana even more confused. Suddenly clasping her hands together, Mem-Cho spoke with a hint of trickery. "Clearly, Ruby couldn't sleep because of troubles of the heart!"

Ruby stiffened even more from Mem-Cho's words, as Kana continued to be confused. "Troubles of the heart…Like…?"

"Like…She has a crush on a boy, or…" Mem-Cho got right next to Ruby's face, her devious smirk fully enlarged as she continued. "She has…A boyfriend!"

Ruby let out a small squeak as she turned her face the other way to avoid Mem-Cho, as Kana was somewhat taken aback by the sudden assertion.

"Huh? Ruby with a boyfriend, that seems a little-" Kana went to refute the argument, yet as she looked down at Ruby's face that was now facing her, and saw how red it was and Ruby's eyes going wide…"Wait…WHAT!? SERIOUSLY!?"

It was Kana's turn to yell out in surprise, as Ruby just buried her face in her hands and attempted to avoid looking at either of them. "I-It's nothing like that, ok!?"

However, despite her words, Mem-Cho stayed on her case as she once again wagged her finger. "As I said Ruby, you're a terrible liar!"

"W-Who is it!?" Kana yelled out as she kneeled beside Ruby, curiosity in her voice as she waited to hear what the young girl would say. "I-Is it someone at school!? A fellow entertainer? Maybe an actor!?"

"Hm…Knowing Ruby, I think her type might be the actor type, someone who also has to hide their life in the entertainment industry." Ruby's blush only deepened as she didn't dare speak, knowing full well she couldn't give any clues at all.

"An actor at our school…Blugh, there's so many! Give us a hint Ruby!" Kana yelled out towards the young idol, who kept her face hidden away as her two idol mates continued to hound her over her sudden inclusion into the world of romance.

As they pestered her, the door to the studio suddenly opened as a familiar figure walked in, as Mem-Cho turned her attention away from Ruby and to the new figure, before her devious expression was mixed with surprise. "Oh Aqua, didn't expect to see you here."

Ruby's body stiffened, making sure her face was still hidden away as she felt her blush only make itself known even more.

Kana raised her head, looking at the other Hoshino who had appeared. "Oh Aqua…Wait…AQUA!? W-What are you doing here!?"

"Morning to you as well, Arima…I came here to watch your photoshoot today."

"H-Huh?! W-What, why!? D-Don't you have rehearsal?!"

"I texted the producer and told him I couldn't make it, it's not a big deal." Aqua gave a rather bland response as he walked over to the three idols, as his attention turned down to Ruby. "What's wrong with her?"

"Hm? Oh that's right, Aqua!" Mem-Cho skipped over to Aqua, her catlike expression having returned as she clasped her hands together. "It seems that Ruby has entered into the world of love! She said she couldn't sleep last night, and after judging her facial reactions, I think it's because she has love on the brain! Do you know anything about it?"

"Love, huh…" Aqua turned his gaze towards Ruby, as she peeked through her fingers to match his gaze as she sunk low into the chair. "...Yeah, I do."

"Ohhh? Tell us!" Mem-Cho slapped her hands together in a begging motion, as even Kana turned her attention to Aqua as she dropped the rehearsal issue for the time being.

Ruby felt her body trembling as she waited to hear what Aqua had to say, keeping her gaze on him through her fingers as he crossed his arms and placed a hand on his chin. "I don't know the full details, but from what I can gather, she has been talking to someone."

"I see, I see, who is it? Do we know him?"

"...His name…" Ruby's chest tightened, as she closed her eyes and waited for- "Is Gouro, Gouro Amamiya."

"Eh? Gouro Amamiya?" Mem-Cho tilted her head in confusion, as even Kana raised a hand to her chin.

"I don't know anybody at our school that goes by that name." She commented loudly, the two of them keeping their attention fixated on him as they awaited for him to give more information.

"He doesn't go to our school, from what I heard he's gearing up to go to medical school actually." Aqua said with a rather monotone voice, as he turned his attention down to Ruby. "Isn't that right, Ruby?"

Ruby looked up once again as she locked eyes with Aqua, and after a moment of confusion, she picked up on what Aqua had set up.

Knowing this was her best chance to get out of this mess, she moved her hands away from her face and slammed them down onto the arms of the chair as she yelled out. "Geez Oni-chan! You don't see me going about and blabbering about your love life!"

"Ohh? So Aqua is telling the truth is he?" Mem-Cho swiftly moved back over towards Ruby, as she poked the girl on the arm. "Soooo, who's Gouro Amamiya? What's he like? Is he handsome? Do you have a picture of him?"

"Mem-Chan, please!" Ruby protested the woman's teasing, her blush still ever present on her face. Still, a part of her was relieved…She had been careless and let Kana and Mem know about her love life simply from being tired, and she had to be bailed out by Aqua.

"Gouro Amamiya…Gah, how did Ruby meet this guy without us finding out about it?" Kana complained loudly before she looked back over at Aqua and squinted. "So, why are you coming to this shoot and not going to Rehearsal to be with your darling Akane?"

"Arima, I've already told you that my relationship with her is purely for work." Kana gave a hand wave that said 'yeah yeah', as Aqua sighed and shrugged. "I just didn't feel like going today, so I decided to check out this shoot you all were doing. I've been in this business long enough to know these shoots can be sketchy, especially for some indie magazine, so I came to check it out and make sure you all were safe."

"Blugh, there's that sister complex again…" Kana said with disgust, before she crossed her arms and turned her back towards him as she walked over to the couch and sat down, grabbing her manga as she opened it back up. "Whatever, just stay out of our way."

"Wasn't planning on getting in your way." Aqua replied tiredly, as he reached inside and pulled his phone. As he did so, he noticed he had a new text message as he opened it up.

Why are you skipping the shoot today? -Akane

Aqua eyed the message, thinking what to say for a moment before he typed in his response.

Ruby has something to take care of today, so I'm keeping watch. -Aqua

Aqua quickly sent the message before dropping the phone back into his pocket as he walked over and sat down in one of the free chairs, crossing his legs as he laid back and relaxed.

He didn't truly know anything about this shoot today, or if he could really spend any time with Ruby.

But, if he was being honest…

It was better than hanging out with a bunch of actors and actresses who didn't care about him, and offered no benefits to him.

Other than the Producer and his Tool, of course.

That's right, his tool.

That's all Akane was to him, a tool to be used to find out Ai's killer.

He didn't hate her or think less of her, but the best way to describe her was being a tool to his revenge.

As long as she did that, then he didn't mind keeping her around as a friend.

But there was of course one problem.

If there was anybody who would be able to figure out his and Ruby's new relationship, it would be her.

That meant that he would have to keep her away from Ruby at all cost, because his sister was too naive around a genius like Akane.

But if Akane ever did figure it out, he would have to keep her quiet somehow. He couldn't ruin his career before he got his revenge, and he couldn't ruin Ruby's dream.

Whether he kept her quiet by dating her 'for real' or even…

He was sure he could do it.

He had to…

Shaking his head as those thoughts invaded his mind, Aqua just attempted to relax the best he could. He stared off into space, as Kana continued to read her manga while Mem-Cho continued to tease the ever flustered Ruby.

Finally, the last member to arrive did so as the door opened as Miyako Saitou walked in, giving a small yawn of her own as she waved towards the girls. "Morning…Um, what's going on?"

Miayko tilted her head to the side, as Mem-Cho turned her attention towards her and smirked. "Morning Miss President! We have some juicy news to tell you!"

"Mem-Chan, nooo!" Ruby protested loudly, as Miyako raised an eyebrow before giving a small laugh, curious as to what was currently going on. As she turned to shut the door behind her, she spotted Aqua sitting in a chair.

"Oh? So you're really coming with us today, Aqua?"

Aqua gave a small nod, his eyes blank as he spoke. "Why would I tell you I was, and then not?"

"Well, I can never tell with you sometimes." Miyako gave a sigh, as she walked over towards her desk and sat down as she turned towards the girls. "Alright girls, what's this juicy news?"

Ruby attempted to protest once again, but Mem-Cho quickly took the initiative and spoke. "Ruby has a boyfriend! Or atleast, she's talking to a boy!"

Miyako seemed taken aback by the news, before a smile spread across her lips as she crossed her arms. "Ahh, so I was right then."

"Hm? You were right Miss President?"

"Well…Last night, Ruby and Aqua got into some argument and she stayed in a bad mood for a couple of hours. After talking to her, I was able to discern it was about a boy and that Aqua was against whoever it was…Seems I was right on the nose."

"Ohhh? Aqua was against it? So you know him personally?" Mem-Cho turned towards Aqua with a devious look, as he sighed and leaned back.

"I've had a couple of run ins with him, nothing more."

"Is that right?" Mem-Cho seemed intrigued and eager to get more information, yet Miyako spoke up once again.

"Although I never got a name, who is it?" Mem-Cho quickly turned back towards Miyako and smiled.

"Seems to be a guy named Gouro Amamiya, and he's attempting to get into Medical school according to Aqua! Have you ever heard of him, Miss President?"

"Gouro Amamiya? Hm…The name sounds kinda familiar, but nothing is ringing a bell right off the bat." Miyako pondered for a moment before shrugging, as Mem-Cho nodded and turned back to Ruby.

"So it's someone the President has heard of and Aqua knows eh? Come on Ruby, tell us more!"

"Mem-Chan, please stopp!" Ruby continued to protest, as the office was as lively as ever, time slowly ticking by as it got closer and closer to when they would have to get ready for the shoot.

As the time ticked away, Miyako turned towards her Mac and began to boot it up, all the while, the name she was just given pestering her. "Gouro Amamiya…Gouro Amamiya…That name…Why does it sound so familiar?"
