A/N: If anyone wants to have a conversation on how to write Aged-Up Todoroki, PLEASE DO! I'm trying to perfect this kid for future fics, because I love him to bits.

I always write to improve, so comments and critiques are welcome! Please rip this to bits! Thank you!

Izuku laughs at the tickling pressure around his neck. "Shouto. Shouto! Stop!"

"I can't, you're seducing me," Shouto mumbles.

"My psychology paper on child development in a quirk dependent society is seducing you?"

"Your intelligent and caring nature that wants to write that paper is seducing me."

"Well, I can't write if you're eating my neck."

"Do you write with your neck?"

"Smart ass." Izuku smiles, rolling his eyes, and just turns his attention back to his assignment. Todoroki drapes onto his back like a stretched out blanket, warm and solid.

"Let me kiss you once, and I'll leave you alone," Shouto says.

Izuku recognizes the dubious request. "The last time you did that, we ended up in the bed for three hours and were almost late for Combat."

"Mmm, then we became sweaty together after class, too." He nuzzles his nose against the shell of Izuku's ear. A hot flush rises to Izuku's neck.

"You have to promise me." Izuku gives a stern look over his shoulder, though the red might have doused the affect. He came to Yuuei University to be the best hero, not the best lover for the top student. "Only once, then you stop. Shouto, promise."

Shouto gives a slow blink, like it's an impossible request to compute, but he must see Izuku's impatience and gives a soft smile that melts Izuku every-time. "I promise."

Izuku turns his swirling chair to face him and captures Shouto's lips. Shouto is more the charming romantic than he could have ever guessed and when he wants Izuku, he wants Izuku. So Izuku is considerate with this kiss- to prove that he notices, he cares, and if quirks didn't exist, if training wasn't so important, he would bask in Shouto for hours.

Shouto moans, a low rumbling grunt, and starts pushing Izuku's chair back. Izuku knows better. He wrestles out of the kiss. "You promised."

"But I love you."

Izuku's brain fries, an overload of information as he wraps himself around the idea, and Todoroki is smiling and diving for him again. A few seconds later Izuku can pull back.

"W-when did you-wait, no, you don't mean that." Izuku accepted that he loved Shouto, he accepted it weeks ago but he never dared to hope it was a two-way feeling.

"It's impossible to know you, then kiss you, and not fall in love, Izuku."

"This is the first time I'm hearing this." Izuku is already melting under him and he's angry, so freaking angry that Todoroki caught him in this trap. Who knows how many times they've kissed, thousands perhaps, yet Shouto thinks now is the best time?

To think, he loves him; this amazing, beautiful-

"You've never resisted this hard before," Shouto admits, shrugging. "You always say love conquers all. I guess that also means your stubbornness."

- devious, manipulative, smart-ass, loves him. And Izuku will fall for him each time.
