Headcanon #1: Kaito smuggled in animals just so Honey could get some relief from his brothers overpowering presence and the stress that came from keeping his title as #1 in Japan when they were in first and second year.

15 year old Kaito Tsukino bit his lip as he ran through the halls. Heavy pants escaped him as his dress shoes thumped on the ground and his brown hair flew in his eyes.

Cursing he stumbled and nearly dropped his bag.

"You wouldn't dare!" A voice howled behind him as he struggled to get into his feet.

"Crap." He flinched and ran faster, turning rights and lefts as the howling voice grew louder.

He turned a sharp corner and pushed open a door before slamming it and locking it.

Kaito sighed in relief as the person could only pound the door and screech at him before he turned around with a wide smile.

"I got them Mitsukuni!" He chirped at the shorter blond who smiled a little at him.

"Thanks Kino," Mitsukuni Haninozuka said in whispered voice as Kaito reached into the bag.

"Kitty!" He announced proudly as Mitsukuni grinned and hugged the mewing kitten.

"You're the best!" He proclaimed.

"Yasuchika is really persistent huh?" Kaito sweat dropped and tried to calm his breathing.

Mitsukuni's face fell and he nodded quietly. "He doesn't think I'm normal."

"I think you're great," Kaito gave a sideways smile before glancing nervously at the door where it got suspiciously quiet.

"Takashi thinks so too but, I don't think a martial arts master should want to cuddle kittens and eat cake."

"You would have an equal understanding of both worlds. Though brawn is strong, gentleness is an equal factor. You can't make a bird sing by smashing your fist, rather use coaxing words."

"Martial arts masters don't get birds to sing." Mitsukuni smiled slowly.

"Well, you are short." Kaito teased.

"What does that have to do with anything?" He laughed.

"Nothing, just wanted to see you laugh." Kaito said cheekily, watching the kitten purr happily. Mitsukuni looking more relaxed than he'd seen in a while.

"Why do you pretend you hate this stuff?" Kaito asked with a frown.

"I already told you, I can't like these kind of things." Mitsukuni rolled his eyes.

"Takashi doesn't care about the fact you like this stuff." Kaito protested.

"But my family does." Mitsukuni said firmly.

"You're going to regret suppressing your urges." He sighed.

"Maybe." Mitsukuni shrugged before handing back the kitten. "Thank you, Kino but I have to go."

"Meet here next Wednesday?" Kaito offered.

"Yeah," Mitsukuni smiled a little at that, "next Wednesday."

Kaito watched him unlock the door and slide out, immediately Yasuchika's loud voice questioning him.

Kaito sighed and shook his head before clenching his fist.

"Now I must complete the perilous journey to Geometry or risk certain death at the hands of Mrs. Toyama for being tardy." He proclaimed to the quiet room before flashing a childish grin down at the kittens and putting a finger on his lips.

"I guess I need to sneak you back to the house too, huh?"

If kittens could meow in exaggeration, this one did.

Headcanon #2: Kaito and Honey drifted when Honey refused to accept what he liked and threw himself into serious practice and foods.

Kaito called out to the shorter blond who emerged from the dojo.

"Hey, Mitsukuni, you didn't show up! It's Wednesday you know?"

Mitsukuni flinched before stealing his resolve.

"I'm not going to do that anymore." He said calmly.

"Huh?"

"I'm not going to sneak visits to pet animals, and I think it would be for the best if we didn't hang out anymore." A hurt look flashed across Kaito before his eyes hardened.

"I see, I guess I never realized you were that tired of me. I'll leave you alone now Haninozuka, hope you feel good about your decisions." He bit out bitterly before turning on his heel.

Mitsukuni turned around and had to stop himself from running to him yelling that he was just kidding and he was sorry.

Instead, he stood there with watery eyes until Takashi walked and stood next to him in a comforting silence.

"You didn't have to." Was all he said.

"I know."

Headcanon #3: Kaito and Mori talked often about how they missed the times where Honey,  Mori, and Kaito would just talk.

"I'm not especially mad, I'm just...offended?" Kaito shrugged and looked up at the marble ceiling.

"He misses you, I do too." Takashi said in his deep voice.

"Hm? That's the longest I've heard you talk in one breath." Kaito teased before frowning. "If he really misses me, why does he avoid me? Is he really that...ashamed of me?"

"No, just confused." Takashi closed his eyes, "Pressure goes to his head."

"I tried to help but he pushed me away." Kaito said in frustration before standing up.

"I'm sorry Takashi but I'm not going where I'm not wanted. Maybe someday it'll be like it used to be."

"I'd like that." Takashi said quietly.

"So would I big guy, so would I."

Headcanon #4: Mori was Kaito's connection to his old friends.

"How's Haninozuka doing?" Kaito yawned as he hung upside down from the sakura tree, kindly ignoring the love confession and rejection that was going on the other side.

"Sad."

"Did Yasuchika say something again?"

"No, saw the annual festival." Takashi said with a tensed look on his face.

Kaito remembered that. Takashi, Mitsukuni, and himself used to go the festival together, Kaito and Mitsukuni would run around like children while Takashi just followed to make sure they didn't hurt themselves and always ended up smiling at the end of the day.

The last time was last year, before Mitsukuni changed himself to please others.

"And how're you doing big guy?"

"Tired." A low rumble indicated he was chuckling.

"Yeah, me too."

Headcanon #5: Even if Kaito and Honey no longer talked, Kaito never stopped looking after him, making sure a cat happened to pass by him on the way home or if anyone talked about Honey and/or Mori, they would go to the infirmary with a broken nose.

"Kaito why did you punch him?"

"He made me mad."

"Why is that?"

"He was born in April."

"So?"

"He made me hate April."

"How?"

"He was born."

He kept to himself that the guy was badmouthing Takashi and Mitsukuni.
