Tsukishima Kei x Reader - Devil

"Good morning, Tsukishima."

"(L/N)," he replied in kind as he went to sit down.

You and Tsukishima were classmates, as far as anyone could tell. Distant classmates at that, since you barely spoke to each other except to exchange pleasantries.

Except it was more complicated underneath the surface. You had gone to the same middle school together, and there was an unspoken competition between you.

You were a mid-year transfer when you first entered Tsukishima's class. Before you'd shown up, he was one of the top students in the class. After a few weeks of you being there, you'd already surpassed him in even some of his best subjects, seemingly without breaking a sweat.

Throughout the rest of middle school, he tried to beat your scores and fell short every time. It infuriated him to no end. So he vowed to keep a close eye on you and find a way to beat you.

After graduating, you ended up at the same high school, even in the same class. It was no surprise to Tsukishima, honestly. However, since he knew he couldn't best you in academics, he turned to clubs as an alternative. You couldn't possibly have any hobbies since you kept your grades so high.

And yet you did it again.

You joined a club around the same time he did and despite being a first year, took on enough responsibility to become a principal member just like his position with the volleyball club.

Even his popularity with girls wasn't enough. Since you were a more approachable person than the dry-witted and sometimes brutally honest volleyball player, you had a number of admirers within the school.

Academics, clubs, and popularity. You had bested him on all counts. He couldn't figure out why he cared so much about being better than you, but he was well aware that it wasn't doing him any good. So maybe it was time to give up and focus on something else.

"Tsukishima?"

He glanced up to see you standing at his desk. "You dropped this earlier." You handed him an eraser.

"Thanks," he said. Had you always been this nice? Was this competition just in his head?

"Of course. You're going to need it."

"What did you say?"

You smiled. "I said, you'll need it. If you're even thinking of beating me, that is."

Tsukishima narrowed his eyes. "Oh, don't worry, I am."

"Good. You can even come study with me if you'd like. Give you a bit of a fighting chance this time."

"You're on!" he retorted, standing up to glower at you. You merely smirked.

"Eight o'clock on Friday then. Don't be late." And with that, you turned around and sat back down at your desk.

Tsukishima slowly sat back down, realizing that you'd tricked him. "Oh...you're good," he grumbled to himself.

You really were the devil in sheep's clothing, constantly toying with him at every turn.

"You're not actually going, are you?" Yamaguchi asked from the next desk over. He'd been a witness to your rivalry for years, and couldn't see it going well.

"Of course I am. I'm going to win if it's the last thing I do."




Weekly study sessions soon became a thing between you, and while he never managed to beat you on your tests, you eventually were the first to confess.

He chose to count that as a win.

And so the dance with the devil continued, with neither of you giving any ground as you continued to best each other at every turn. And that was the way you liked it.
