You’ve always had enemies growing up so it wasn't a surprise when you met Eirian, but…you never had an enemy like Eirian.

You first met Eirian when you both joined the baseball team, at first you two were friends, you two were changing in the locker room one day and things turned a little- well actually a lot…intimate. You were loving the moment, the only sound being skin-to-skin contact and the moans and grunts coming from you two when you heard a sudden noise, and out of fear you told him to stop, he did but he seemed agitated by that. You have zero clue when this rivalry started but you just went along with it, for years you were in silent but obvious rivalry with Eirian. No matter what it was, no matter how easy or difficult, you two would compete to be better at it, sometimes he won or you won.

Your friends invited you out to eat, and when you got to the restaurant you saw Eirian with them, every seat taken but the one next to him. You were immediately ready to go home but you weren't going to let one person ruin your whole night so you sat down. The two of you were mostly quiet and refused to look at each other, though you didn't see him you could hear the clink of the bottle he was drinking, after a long moment Eirian suddenly leaned a little closer and whispered in your ear.

“Why so silent pretty boy? Y’know…I know a lot of ways to make you scream.”

You knew he was just saying this because he was drunk but you couldn't help but get a little flustered.
