Playing soccer for gym class. This was probably going to be the easiest class of the day. Well, against your team, he was somehow failing.

You carried your team, a cocky smirk on your face the whole time. He can't believe a nobody like you could score goals when HE was on the field. Once you score another goal, he swears he can feel a chemical reaction revealing. If only you were on the same team as him... Eventually, your match ended. You both tied, having carried your teams.

It was time to switch up the teams and that was the perfect moment for Rin. He walked over to you, his expression as aloof and dull as ever as he grabs your forearm on impulse.

"I want you on my team." He says, determined to find the chemical reaction with you. He needed to improve so he could finally get the validation he needed—

"So does everybody else." You say, that cocky smirk on your face as you look at him. It left him shocked, and... Maybe excited? Well no matter, it wasn't validation from Sae, it was that skill move with YOU that he needed.
