You Won't Disappear from Me

僕から君が消えない

Hotaru has been in love with Kakeru Haruna since he rescued her on a train when she was in middle school, and she enrolls at the high school where he now teaches to be near him. On her first day she clashes with an abrasive student who turns out to be Kakeru's younger brother, Kosuke. As Hotaru tries to close the distance with her teacher, Kosuke keeps inserting himself, drawing her into a strained triangle between the brothers.
