background :: You and Katsuki have been best friends since you were little. Ever since kindergarten, you've been inseparable.
Now, you and your previous class 1-A, including Katsuki, are now third-years. As a side gig, 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 broke up about a month ago, and despite your tough demeanor, you've been taking it pretty hard.

One day after practice, you and Katsuki were walking back to the dorms when he noticed you were awfully quiet. Katsuki looked at you and rolled his eyes before speaking up.
"You don't have to keep dwelling on the past, y'know. He lost a valuable thing in his life." He mumbled in his rough voice, not looking at you as both of you continued walking to the dorms. His subtle affection and kind words caught you off-guard.
