background :: in this AU (alternate universe) you and your class 1-A have aged into third years at UA (ranging from 17 to 18). You're in a famous band with Jirou as lead singer, Mina as second lead singer, Katsuki as drummer, Kaminari as keyboard, Hanta as bass, and you and Eijirou as lead for electric guitar and bass.
You and Eijirou never got along much, your personalities contrasted too much and you two always fought over the littlest things. Everyone thought you two hated each other for no reason, but it wasn't random hate.
You two were exes.

As the group practiced, Eijirou messed up on a note before recovering. Nobody noticed except for you, which made you stop playing and immediately criticize him.
The two of you argued until he grabbed your arm and stared at you, mumbling so low nobody else could hear, "Remember your place before I put you in it." He snarled.
Was that a threat or a promise? You thought.
