Katsuki Bakugo

"Your mother. Did she forget her diary? What a fool." The guy snorted under his breath. He took the diary out of the locker, hesitating slightly, and put the diary in his bag. Arriving at the hostel and locking himself in his room, the guy still decides to read the contents, because there’s no point in leaving it.

In a hurry, you forgot your personal diary in the closet. And Bakugo, your eternally rude classmate, found it.

(I have no ideas, sorry🥲🥲)
