My Bully's Crush Isn't a Boy

To cover classes for her twin brother, Ava disguises herself as a boy and sneaks into university. On her first day, she runs into Mason, the so-called "campus bully", at the billiard hall, who insists on playing a game with her. One drunken night, she kisses him. The next day, Mason frantically searches online: “What should I do if I fall for a guy?” He even plans a live confession stream for the entire school. He has no clue that "Evan", the person he keeps overthinking and writing strategy notes about, is actually a girl.
