Alright, the sequel is here! Enjoy!

After Summer and Tsuna started going out, everyone was happy for them...except for one person.

Kyoya had avoided the two for a long time, only seen around the two when absolutely needed. But, as the years went on and he matured, Kyoya seemed to accept it. Though he did say to Tsuna's face, "If you die or disappear, know that I'll take what should have been mine," he acknowledged the relationship.

Now, ten years later, it came time for Tsuna to "die" and be buried. Summer, although very reluctant, had agreed to the plan. It was decided she would stay at Kyoya's base to "mourn and calm down", so she wouldn't have to keep acting at the main house and/or accidentally spill the beans. No one should question it since it was at Tsuna's hometown and was secluded.

After all preparations were made, Tsuna was killed.

Summer's acting was topnotch. When the news had arrived, she fell to her knees and cried out, catching everyone's attention in the house and spreading the news fast as she was the first one told, being Tsuna's lover and all. (And no, they were not yet married. Tsuna wanted to wait until he had made the Mafia better before settling down.) After crying her eyes out and screaming until her voice was gone, Summer remained despondent for the days to come. Then the funeral happened. It seemed all too real at the exact moment Tsuna's coffin was being taken away, and Summer had ran to the coffin unconsciously, crying for him to wake up and come back to them, to her. She had to be pulled away by Takeshi, who kept a hard look on his face while tears ran down his cheeks.

Kyoya, on the other hand, took to keeping his distance and a blank face. Though he did get yelled at for not properly mourning and even accused of not caring for their boss, Summer knew that if Tsuna actually died, that is most likely how Kyoya would respond. He wasn't the most emotional person in the first place.

A few days after the funeral, Summer announced she would be staying at Kyoya's base in Namimori to get her head straight and visit the Sawadas for a while. No one argued, thinking it was the best for her. She was only told to be careful and take care.

Then it was time to wait for their younger selves to appear.

As they waited, Kyoya and Summer usually just lounged around on his side of the underground base. It was a good time for the two to reconnect and talk about how their lives have been since Tsuna officially became the Tenth, since everyone was more spread out. And when they weren't talking, they would just sit in silence and drink peacefully, waiting.

And when young Tsuna finally showed up, Kyoya didn't like it. Not. One. Bit.

When the boy came in, Summer's expression immediately lightened up and she ran to give him a long, long hug. He should the one in her arms, not him. And as the days went on, Summer was slowly slipping away from him...

...Again.

—

"Hey, Kyo, you okay? You seem a bit more irritable since our younger selves showed up." It was one of their late night drinking session where they would sit beside each other and watch the fake, but beautiful, cherry blossoms.

"I'm fine." Kyoya just kept staring at the scene before them.

"No, you're not." Summer pouted as she placed her cup down beside her.

"Yes, I am." Kyoya growled before taking another sip of his sake.

"...Kyo, look at me." Kyoya didn't move. "Kyo." Summer lightly grasped his shoulder, making him look at her out of reflex.

What he saw was the most enchanting scene he had ever laid eyes on. The dim light coming from the fake night view of the cherry blossoms had highlighted Summer's smooth skin. Her eyes seemed to glitter in the fake moonlight. The way she was looking at him, like he was the only thing that mattered, took his breath away. And the way the light hit her body and outlined all her features made his mind go blank. Animal instincts started to kick in. All that was in the way was a few pieces of clothing.

He lost it.

"Kyo-" Before Summer could continue, Kyoya was on her.

He jumped on her and started kissing her like mad. Summer, caught up in the moment, kissed back. Old feelings rose back to the surface. Kyoya groped her chest, pleased to find she wasn't wearing a bra. Summer moaned under him as he kissed down her neck to her chest. But, just as Kyoya went to remove the hindering piece of cloth, Summer caught his hand.

"We-I shouldn't do this." Summer panted, making Kyoya clench his jaw but also turning him on. The way she looked, all flushed and out of breath, made him want to ravish her more. "Kyoya, although he's not here right now, I have Tsuna."

"You said it yourself, he's not here right now." Kyoya took the hand that was grasping his and kissed the back of it. Summer pulled it away.

"Kyoya! That would still mean I cheated on him!" Summer moved to sit up, but Kyoya didn't move. "Kyoya, get off." Ah, that glare. It only made him more thirsty. He leaned down, forcing Summer back on her elbows.

"I don't want to." Kyoya whispered in her ear before giving a little lick. Summer flinched. "And you don't want me to either." He murmured between the crook of her neck and shoulder. Summer gasped before swallowing hard.

"Kyo-YA!" Summer yelped as she felt Kyoya's tongue and something poke her stomach. "NO!" Summer pushed Kyoya off, earning a growl.

Summer quickly got up, only to fall down again as Kyoya grabbed her ankle.

"Kyoya, fuck off!" Summer yelled as she flipped around to kick his hand off.

"I'd rather fuck you." Kyoya caught her other leg and pinned Summer down in a flash.

"Kyoya! Stop!" Summer screamed as she struggled against his grip, accidentally brushing against his crotch. She froze as he groaned in her ear.

"Don't sto-" As Kyoya looked at her, he paused.

Tears were welling up in Summer's eyes.

"Tch." Kyoya get off of Summer and left the room.

—

After that, Summer kept a distance and stopped coming to their drinking sessions all together. Kyoya knew he screwed up, but what could he do to get her back?

He had to apologize.

But the Strongest Guardian never apologizes. Not even to Summer...

...But, it was either his pride or Summer. And he knew what the right choice was.

So, he approached Summer while no one was around and asked her to join him and Ryohei for a drinking session. She hesitated but agreed as soon as she heard someone else would be there.

As the time came for the session, Kyoya waited patiently for Kusakabe and Summer to show up.

Once Summer slid the door open and saw no one else there, she closed it. Kyoya just took a few sips of his sake as he listened to Kusakabe persuade Summer to stay. Soon enough, she entered and sat down across from him, a table between them. Kyoya silently offered her some sake. Summer, although cautious, gladly accepted. And after a few drinks in silence, Summer relaxed. Kyoya took one more sip before...

"I apologize." Kyoya's voice cut the silence and his words hung in the air as Summer took her sweet time comprehending what was just said. When she finally did, she smiled.

And at that moment, Kyoya realized he would gladly apologize a hundred times if it meant having Summer smile at him.

—

The days went on, and it was like nothing ever happened. Soon enough, it was time for the fight against Millefiora. And after everything, it was time for the younger ones to go back.

It was time for their Tsuna to come back.

Summer was the first one to run to the casket. Kyoya was the last. And as he arrived, his feeling of accomplishment was drowned away by the feeling of jealousy at the scene before him. Summer was in Tsuna's arms, and she was kissing him.

She was willingly kissing him.

And who knew what else she would willingly do with him tonight.

The thought made Kyoya sizzle inside, and he walked away without so much as a glance to his boss, who had just risen back from his coma.

Why should he when what should have been his was taken by him?

—

That night a party composed of close friends was being held. Kyoya was required to go by that omnivore he came to despise once again.

In the middle of the night, when most people were drunk, Tsuna pulled Kyoya into the garden, making sure no one was around.

"I just wanted to say thanks for going through with my plan, and, uh," the omnivore still stuttered around him, "keeping Summer company," he would have gladly done that without him even asking. "She told me how nice you were," really, "and how she would be happy if you visited and stayed around more," did she now? "So, thank you. I don't know how I could ever repay you, Kyoya," Tsuna finished with a genuine smile. Kyoya stared back blankly before a thought popped up.

"Give her to me."

Silence.

"...E-Eh? I'm sorry, but what did you say?" Tsuna's smile faltered.

"I said, "give her to me."" Kyoya nonchalantly repeated. "She should have been mine." Tsuna dropped his smile and slightly glared.

Oh, the omnivore's fangs were showing.

"Kyoya," there's that tone people described as intimidating, "you know I can't do that."

"Hn? And why not?"

"As I was going to tell you, and only you, I'm going to propose to her soon."

...

"No."

"No?"

"No. She doesn't belong to you." Kyoya glowered down at his boss.

"Yes, she does. And once the ring is on her finger, it will be official." Tsuna met Kyoya's glare with his own, not backing down an inch. "And you can't stop me."

"I can. All I have to do is make her mine." Kyoya smirked.

"In case you've forgotten, she chose me over you years ago!"

"She can change her mind." Tsuna looked away and rubbed his temples in frustration.

"Since I see you wont give up, how about we make a deal?"

"Deal?"

"If you can get Summer to tell you she loves you in a month, she's yours." Tsuna seemed to be chewing his cheek, not liking this. "If she doesn't, you have to back off and consent to our marriage."

"Deal." Tsuna's eyes widened.

"W-What? Aren't you even going to think about it?!"

"It's a simple deal. What is there to think about?" Tsuna seemed to revert back to his younger self for a second as he shrunk and jittered like he usually did back then before shaking his head and looking serious.

"Fine. Your month starts tomorrow. You have thirty days." Tsuna walked away with his hands clenched.

Kyoya smirked.

"She'll be mine soon."

That's a pretty good first chapter, I'd say. I'd also love to hear what you guys think! Until next chapter, whenever that'll be. Bye~
