Her hair.
That was Tadashi's favorite thing about Honey Lemon. Not her eyes, her bright personality, or even her lips (although all of them he still thought were absolutely wonderful). Her hair was simply amazing, whether it was up in some complex-looking hairdo, or down. And it wasn't all just one color, either. Her hair color varied with every individual strand, which he honestly didn't know was possible. But the worst thing about her hair was this:
Honey Lemon didn't like people touching it.
She always freaked out when someone tugged at it or tried to touch it, probably because people had resorted to trying to sneak up on her to try. And by people, I mean Fred. He was the only one of the group who had the guts to try. The rest of them simply respected her odd wish and moved on.
Except for Tadashi.
He just couldn't stand being around Honey Lemon all day long and not being allowed to touch her hair. Whatever she was doing, whatever state it was in, he wanted to touch it. He didn't care if it was up, down, frizzy, sleek, wavy, or straight. And he was probably going insane over it.
He often caught himself starting to reach out toward it more than once. He would then quickly snap back his hand and look to make sure that no one had noticed. Cue the sigh of relief. It was a cycle at this point, and with each failed attempt, Tadashi grew more and more restless and frustrated. How was it possible to be driven this insane by just hair?
But finally one day, he succeeded.
He and Honey were the last ones in the lab- as usual. Both were extremely dedicated to their respective projects and wouldn't go home until they felt that they'd accomplished something that day. Seeing as how Tadashi was done with Baymax for the day, he decided to sit and watch Honey Lemon so she wouldn't be alone.
And there it was. That luscious, flowing hair. It was as if it was laughing at him, saying "Uh, uh! No touchy!". It drove him crazy.
"Hm…I really should put my hair up before I continue…" Honey Lemon mumbled to herself. "This acid will burn right through it." She walked over to a drawer and pulled out a hairtie.
Tadashi's eyes widened. "Here, let me help." He didn't even know what he was saying at that point- the words came out completely on their own.
She blinked her wide eyes. "Oh, um, okay." She dropped the hairtie in his hand and turned around.
He held his breath. He couldn't believe this. He scooped her hair up into his hands and nearly let out a sigh. It felt as soft as he'd always imagined. He went through the motions of putting her hair up into a ponytail, definitely taking his sweet time. When he was done, her let her hair slip from his hands with a sigh.
Honey Lemon turned around and played with her hair. "Thanks," she said with a blush.
Tadashi couldn't find words. He simply nodded and sat back down.
