chapter 2 summary: Truths were revealed except to Iruka. Now, Kakashi and Iruka were given the task to take care of him, and Iruka was left wondering why does he have to take care of the son of a jounin he was quite in love with?

Iruka thought, his hidden feelings for a certain jounin were bad enough, well it wasn't.

It was just a normal day, summer's around the corner meaning, in a few more days, Iruka won't have to think of lesson plans every single day for the next three months. The sensei had already said his goodbye to his class, wished them a well and fun summer while the little hellions only cheered and walked out of the room, all ready to play under the sun and with their friends.

After gathering his stuff, he planned to get some tea first before heading home. He also wondered if he should buy some vegetables or take-out because honestly, since it's the last day of school, he's feeling quite lazy and ramen for dinner doesn't sound so bad.

And that's where an ANBU suddenly appeared in front of him, immediately making Iruka nervous.

He had thought about all the possibilities of why he's needed at the hospital, and his first thought was Naruto. He had just left months ago and—was he injured? Did he come back because they were attacked or something?

His second thought was Kakashi.

Ever since then, he and the jounin had this very funny relationship where they're friends, but not at the same time. It was complicated really, he couldn't pinpoint what their friendship really was but Iruka was sure he cared for the other, the same goes for Kakashi.

In the midst of his thought, Iruka gave the ANBU a nod and took a U-turn towards the hospital.

The moments he arrived, he froze. In front of him were two Kakashi. Well, that's what he had seen first since the one on the bed and the jounin by the window looked awfully the same. But, as much as the young boy looking so much like Kakashi, he still had this look of a young, scared boy staring back at him.

With those pretty brown eyes.

"You called for me, Tsunade-sama?" Iruka said after he bowed. The Hokage nodded and called him forward, which the chunin-sensei did whilst observing the absence of ANBUs around. When he stopped near the bed, he couldn't help but to be sucked into those brown orbs of the boy resting on it.

"Mom?" The boy whispered but Iruka heard it clear. Iruka was perplexed at first, not understanding what was happening, but based on the IV connected to the boy's arm, and the cooling patch on his forehead, the teen must be sick.

Iruka then looked up at Kakashi, hoping the jounin could explain what was happening, and why was he here, and sadly, he only received silence as an answer.

The boy on the bed cleared his throat and Iruka's attention was immediately on him again. He slightly reminded him of Naruto.

"You're… Iruka-san?" He asked weakly, eyes glossed and lips formed into a pout. Iruka faltered for a moment before nodding. This kid somehow made him feel cautious and he doesn't know why. He's usually not cautious when it came to kids but now.

"Iruka," Tsunade spoke, voiced laced with authority and seriousness. Iruka straightened up and averted his gaze back at the Godaime, "Yes, Hokage-sama?"

"I will assign to you to take care of this kid. He will be under your care together with Kakashi,"

Iruka swore his cheeks heated at the mention of Kakashi. On top of that, when he looked at the jounin, the other wasn't complaining. Usually, Kakashi would—no, should complain. Why would the Godaime assign to him a kid he doesn't know? And with Kakashi?

"Uhm, if you'll excuse me Hokage-sama, who is this kid?"

"He's my son," Kakashi finally spoke, removing himself from the window as he walked up to the boy on the bed.

The word 'son' kept ringing in his ear, and the drop of his heart at the pits of stomach didn't help either.

Kakashi has a son.

Wow. Iruka felt like a broken-hearted high school girl at the sudden confession. His long time crush already has a son, meaning Kakashi also had someone he loves—

"From the future. He's from the future, Iruka-sensei," Iruka blinked and then looked at the boy again. "His name is Sakusa,"

"Hello, Iruka… sensei," Sakusa blushed and covered mouth with his hands.

It was the first time Iruka got to notice his features. He did look so much like Kakashi, but his eyes weren't his, and the beauty mark under his right eye just added more charm to his already good looks.

But the heaviness in his chest didn't fade away. Still confused as to why Kakashi's kid from the future was here, and also bothered by the fact that Kakashi would end up with someone who can bear and offspring.

Of course.

"C-can you tell me how he got here?" He asked, voice breaking a little as he tried to push away the hurt, hoping no one could notice how the information of Kakashi having a son totally drained him immediately.

"He told us that he had stepped on some scroll in the Hokage Tower and then suddenly, he was transferred here at our time. The reason I called you was to help Kakashi for a while in handling this rascal until we figure out how to return him," Tsunade walked over to Sakusa and ruffled those wild locks.

"This will be considered a mission, and funds would be given every two days,"

"B-but, Tsunade-sama. Where would he stay?"

"You two can talk about it," She smirked, eyes pointed at Kakashi who looked as flustered as Iruka. "Before I go, I expect that none of this would go out. Only the three of us knew of his situation."

Iruka nodded stupidly while Kakashi remained stoic.

"You're the perfect choice Iruka-sensei because I doubt that Kakashi could survive handling a kid that looked so much like him."

As Tsunade did a final check-up on Sakusa, she left with a promise of sending in the mission scroll for the two of them.

Well, that was quite a blow. Iruka stared at Sakusa for a moment, and then at Kakashi. Both men were quiet and the chunin-sensei couldn't help but to release a sigh afterward. "Well, uhm… Sakusa-kun, how are you feeling?" Iruka asked softly, and weirdly enough, the boy only stared at him as if there was something on his face. It made him uncomfortable, really, like those big, brown, beautiful eyes of the kid were looking through his soul. His very core.

Sakusa coughed, breaking off their little staring contest. Iruka immediately went near to tend him, rubbing soothing circles on his back and gently laying him back down on the bed.

"You better rest up," Kakashi spoke but the distance between him and the bed was still increased it made Iruka frown. Kakashi should show more concern for his 'future' son but he couldn't blame him. The jounin might've been as shocked as he was.

Soon after, Sakusa was asleep again and Iruka managed to pull Kakashi out of the room.

"Kakashi-sensei… All of these just happened so suddenly but why me? You could've chosen others to take care of him, and I know school's over but I still have paper works and the mission desk—"

"Iruka-sensei, I – I know this would be a lot to ask for but the only person that I know who could help me with this is you," The desperation in Kakashi's voice was mixed with calmness that it made Iruka curse internally because he knew he wouldn't just turn down someone who needed help.

"I—Sakusa is still a kid and you're the first thing that came to my mind, please. I'm sorry if I got you tangled with me but I promise, I just need help with a teenager and I will do the rest,"

Iruka gave him a look for a moment, observing how the jounin's exposed eye looked sincere and helpless. It wouldn't hurt to help Kakashi and his son.

It stings but it's also unfair to leave a friend behind.

With a defeated sigh, Iruka nodded. "Okay, I will help you,"

And Iruka knew, even under that mask, Kakashi was smiling at him. And Iruka hated the fact that even though he hadn't seen Kakashi's face, he knew what the other was expressing—hell, he even fell for that mysterious jounin.

But still, the thought of Kakashi having a wife in the future was like a heavy brick on his chest.

"May I ask, Kakashi-sensei," Iruka started, "How are you so sure that Sakusa really is from the future? And not…"

"Maa, he said some personal things that even the Hokage doesn't know, and that—well,"

"Sorry, you don't need to answer that," Iruka replied sheepishly causing the jounin to chuckle, "Well, another thing was that the kid broke inside the Hatake Manor,"

That was definitely something. Today had been a long day and Iruka just wanted to rest and just maybe, eat chocolates to cover up this messy heart of his. He gave Kakashi another smile, "Okay, Kakashi-sensei, I think I will see you tomorrow,"

"Stay at the estate,"

"What?"

The jounin sighed, one hand coming up to scratch the back of his head. "Stay at the Hatake estate so it won't be a hassle for you to come and go. I—there's a lot of spare room, and the furniture is still quite intact so—"

"Okay,"

The jounin's eyes met Iruka's.

"Okay?"

"Yes, okay. Now if you'll excuse me, I need to rest and maybe pack up,"

⋆｡˚ ┈┈┈┈ ˚｡⋆

It was almost three in the morning, and Kakashi remained restless. He had sat by the window, watching his proclaimed son sleep peacefully. He might've acted so lightly about it earlier, but the truth was, everything that's happening confounded him.

Him, the Copy-nin, the friend killer, had found happiness in another dimension, and now Sakusa has come to his world where he knew he won't be able to find his own happiness.

He felt slight jealousy for the other Kakashi—Sakusa's real father. He had a new family, with a son a wife whilst here was Kakashi, stuck and alone.

Sakusa looked like him so much. He also has a hint of Sakumo's face.

This child was a Hatake.

It angered and pained him. The Kakashi, Sakusa's real father, was happy. He has a son and apparently was married to the female version of Iruka.

Speaking of Iruka.

Kakashi inwardly sighed. The small feelings he had for the chunin-sensei was his most valuable secret, but who knew those said feelings would also be dimensional. Does it mean something? Would it also be possible to have something with Iruka?

"Iruka Hatake… Umino, my mom," When that name escaped the young boy's lips, Kakashi blinked at the kid stupidly. He wasn't sure if this kid was fucking with them, but Kakashi hoped he had heard him right.

He said Iruka Umino was his mom. Or what he said—Iruka Hatake.

Kakashi would've believed him if it's someone he knew, and if it was a woman, but Iruka? As his mother?

But Iruka Umino was a man. Has been since he was born and taken care of by the Sandaime. So why would this kid that claimed to be his son, now claimed Iruka as his mother? He got to be kidding him.

"Are you fu—Iruka?"

"Yes…" Sakusa answered groggily but he started to sober up when Tsunade helped him to sit up straight. "Was it bad that I told you guys who my mom is?" Sakusa's eyes then landed on Kakashi, worry was printed on the younger one's face. "Are you and mom not—erm, together yet?"

"Yeah…" Kakashi could only answer before following another question, "Were you adopted?"

"What? No! I'm a full blood Hatake,"

Tsunade finally snapped out of her trance and gave the kid a very annoyed face. Yes, leave it to the Godaime to bring out the truth, Kakashi thought.

"Hey, I have taken care of you and you have bothered Kakashi enough. Tell us the truth," She muttered through gritted teeth, resulting in the kid looking a little afraid. Kakashi couldn't interfere though, he too, wanted the truth.

"Speak the truth, kid. Spit it. It won't do you good if you're like this to the Hokage,"

"I- I'm not…" Sakusa answered weakly, cowering away from the Godaime. "I'm telling the truth,"

"What do you know about your mom?"

"Uhm, well…" Sakusa started, eyes looking down as he played with his fingers, "I was born in winter, uhm. You and mom were married in spring just after Naruto oji-san's wedding and, and—mom is the headmistress at the Academy, but since I'm in the past, she's still a teacher. And her parents died when the Nine-Tails attacked,"

"Naruto? Wedding?"

"Shit, am I not supposed to say that?" Sakusa looked up at them with a pout, eyes glassy as if apologizing to them. "Am I –"

"How did you get here?" Kakashi asked.

"Okay, yeah… storytime," As Sakusa explained to them what happened on that day, every passing second had Kakashi gaping. The mention of them enjoying breakfast at the manor, him cooking for them, and Sakusa helping out at the Hokage Tower.

Kakashi's heart fluttered when he said that their Hokage was Naruto. It won't be impossible for him to be one in this dimension either. And as the story progressed, he kind of concluded that Sakusa wasn't from this time or dimension. Sakusa must've come from another world where Iruka was a female and his mom.

His eyes and expressions screams like Iruka too much at this point.

"And I went to the manor because… because if dad was with me, he would tell me to go somewhere who I can trust, and it's you," His eyes landed on Kakashi before looking down again, "I'm sorry for breaking in but your barrier was pretty easy to break,"

"Excuse me," Kakashi cleared his throat, "My barrier is a jounin level,"

"Well you thought me how to dismantle it so," Sakusa shrugged and grinned at Kakashi. "Also, is my hair not enough? Dad always tells me he's like looking in a mirror whenever we talk."

Tsunade released a tired sigh after, probably having a migraine. "Look, let's go back to the topic including Iruka,"

"What about mom?"

"We need to make sure that you're related to Kakashi or him, but Sakusa, you technically did travel back in time but—not really." Tsunade started then looked at Kakashi. The jounin nodded, he knew where Tsunade was headed with this conversation. "You see, our Iruka here is, how to say this, not able to conceive,"

"What?"

"In other words, Iruka Umino is a man,"

"Wha—"

"I think you traveled to another dimension or another reality because I assure you, Iruka is a man." Tsunade's eyes held sadness as she looked at the devastated face of the young lad. It seemed that everything had connected in Sakusa's brain, and Tsunade felt sorry for the confused teenager.

"So… I won't exist here?"

When Tsunade nodded, Sakusa exhaled heavily. The thought of landing somewhere back in time was heavy enough for him but in another reality? His mom wasn't his 'mom', and his father doesn't really trust him and—

"Will I be able to come back?"

"That—that I don't know," the dejected look Sakusa gave moved something in Kakashi's heart. It was weird, feeling something for a stranger that claimed to be his son from another reality, that is.

Amidst all of that, Kakashi's just glad that Sakusa agreed to not tell Iruka the truth… yet. It was enough that the Hokage knew of the truth and adding more people right now might be dangerous. He wasn't saying that Iruka wasn't trustworthy, Kakashi was just worried. He had no idea how Iruka would handle the fact that he also had a son—that he bore a child because he's a woman in Sakusa's dimension.

The boy looked heartbroken enough if Iruka would react negatively.

After a few hours, the sun started to rise up, at the same time, the boy began stirring lightly. Kakashi watched intently as Sakusa scrunches his face for a while before slowly opening them up.

"Dad?" He called out once his eyes landed on him.

"Still stuck, kid." Sakusa pouted at the answer and Kakashi took this opportunity to pace himself towards the kid. He suddenly leaned down, intimidating Sakusa as he pushed his headband up, showing his sharingan, "Listen, I still don't trust you." Kakashi started as Sakusa gaped at the spinning Sharingan, "You need to prove me more if you're really from the future,"

Honestly, most people would feel scared right now but Kakashi's impressed on how the kid was handling this calmly, but the little sweat on his forehead wasn't unnoticeable.

"Okay, I get it."

"Once you're free to go, I will test you and make sure you won't be able to cause any wreck in this village. If I ever found out you're faking—"

Kakashi stopped. Then frowned once he realized that he had just threatened a kid.

"Just… I'll see to it that we'll be able to take you home,"

"I know you will, dad"

"Stop, Kakashi is fine,"

"I told you it's so weird to call you by your name,"

"Stop."

Kakashi sighed as he moved away from Sakusa. He then pointed at a covered tray on the nightstand. "Eat that up and then rest. Tsunade will come to check on you again whether we can release you today or not."

⋆｡˚ ┈┈┈┈ ˚｡⋆

First things first, Iruka was slightly panicking. And maybe still confounded. He had just gotten home from the hospital and he was foodless. He had forgotten to buy some vegetables and meat, and now he was stuck seated on the table, waiting for instant ramen to cook.

Kakashi has a son. From the future.

Time travel existed, and somehow Sakusa got here. That thought alone made Iruka so tempted to ask who Sakusa's mother was. The kid was the spitting image of Kakashi, and what hurts him more were Sakusa's eyes looked so warm, so beautiful.

Iruka concluded he got those eyes from his beautiful mom.

Kakashi would marry someone so worth it.

Iruka exhaled a little too loudly as he checked his instant ramen. Tsunade-sama just assigned him to take part in taking care of the kid, sure it was easy but it was Kakashi's kid. And now, he also needed to live with Kakashi.

Iruka had liked Kakashi for so long. It started somewhere around the beginning of the chunin exam where he went berserk against the jounin, and he thought they would not talk anymore after that, but he was wrong. They continued to talk and Kakashi even praised him for standing up for his students' welfare.

Yeah, maybe that's it. But the breaking point was when they have failed to rescue Sasuke, Kakashi had quietly gone to him at midnight and broke down his thoughts to him.

He had seen a fragile Kakashi and it made Iruka fall in love more with the jounin.

Living with Kakashi and his kid. Iruka was partly nervous and maybe a little excited. His friends had always told him he just needed some closure to the jounin but Iruka just couldn't. He's just a mere chunin, not even close to the strength and level of Kakashi.

When his ramen was cooked enough, Iruka took his chopsticks and dived in. He needed to pack and get his shit ready.

This was just a mission he needed to fulfill.

Nothing else.

⋆｡˚ ┈┈┈┈ ˚｡⋆

"Hey, uhm… dad," Sakusa called out, unsureness was in his voice. Tsunade had come by a little early than planned, checked his vitals one last moment before deeming the boy good to go because they needed the hospital bed. She had also reminded them that what they were doing was classified as an S-Rank mission, and made Sakusa swore to not be nosy.

Kakashi thought, maybe he really was a Hatake because he seemed responsible enough. They had learned that he was fourteen years old and Kakashi was more impressed to know that he was already a chunin by ten.

Now, as the two of them walked their way towards the Hatake Manor, Kakashi couldn't help but grin as he glanced at Sakusa. The poor teenager wore a usual flak jacket, different from the one he had one yesterday, but his undershirt had a hoodie that hid his wild hair perfectly.

Kakashi commanded to keep the hoodie on at any time or he'd be forced to cut his hair bald.

"What?" Kakashi answered nonchalantly.

"You said you needed proof whether I'm your child right?"

"Not right now, your chakra's still low."

"AH! I got it, what if I summon one of the ninkens that are from my dimension and maybe they could help us?!" Sakusa shouted, arms wide open as he looked up at Kakashi hopefully.

"Wait, you can summon my ninkens?"

"That's the first one you have taught me, duhhh," Sakusa rolled his eyes as he stood back, giving himself a wide space.

Iruka, who had just heard that Sakusa was already discharged, decided to visit them on his lunch break and luckily, on his way towards the hospital, he seemed to have stumbled upon the duo. He smiled, saw Sakusa backing and something tells that the kid was up to something no good.

Iruka slowly walked closer, eyeing the duo until Sakusa quickly bit his thumb.

Kakashi watched in amusement.

"Summoning Jutsu!" After those words were said, a big puff of smoke came out and covered the teenager. Both adults waited for a moment.

Kakashi's heart was beating loudly against his chest, waiting for an exact copy of his ninken or something that could be enough proof that he really was his son. However, as soon as the fog cleared up, they found Sakusa seated on the floor with his hair disheveled as if his own summoning exploded right in front of his face.

"Wh-whaa…"

Kakashi just sighed and took notice of Iruka in front. "Oh, sensei," He greeted with a salute and Iruka greeted back with flushed cheeks, not expecting to be noticed soon.

"Sorry about him, he's an idiot," Kakashi shrugged.

"It didn't work!" Sakusa whined and Iruka decided to walk towards the poor boy before holding out his hand. "Come on, stand up."

"I told you you're still low on chakra. You didn't listen. Jeez, I didn't know my son would be this hard-headed," Kakashi commented and resumed his walking, leaving them behind. Sakusa could only stare at Kakashi's back with a scowl, not liking one bit of the embarrassment that just happened to him.

"Sakusa," Iruka called out, causing the teen to avert his face at Iruka.

So this was really the male version of his mother. It was still her. This Iruka here still emitted the same gentleness as his mom.

Sakusa then proceeded to grab the awaiting hand, rough but warm, and Iruka gently pulled him back up to his feet. "Are you okay?" His mother's alternative self asked, brown eyes looking around his body for any light bruises.

"Yeah, just… a little weak," Sakusa couldn't help it. Iruka was his parent. And he missed them.

"Well," Iruka smiled gently, "Let's get you walking,"

"Y-yeah…"

⋆｡˚ ┈┈┈┈ ˚｡⋆

It was weird. For a moment when Sakusa looked up at him, it reminded him of himself. Those brown orbs that seek attention. Like when Naruto was young, how he looked up at him with begging eyes.

Sakusa was something and Iruka was to figure out what was up with that kid from the future.
