Sensei, Kiite yo

A student initially believes her homeroom teacher is a dork but discovers he has a different side when she sees him dressed otherwise. He is secretly a rock-n-roll performer. Wanting a boyfriend, she blackmails him into dating her by threatening to expose his secret, but she ends up genuinely falling for him. A separate one-shot story follows a girl who avoids visiting her estranged grandmother and plans to spend the O-bon festival alone, only to encounter someone unexpected.
