Hinata Asahi is a high school student who lives alone with only her teddy bears to keep her company. Her life becomes much more exciting when the handsome Shirou Asou, moves in next door – not only is he really cute (even if much older), but he’s also her new teacher! Hina has a bit of a crush on Asou-sensei, but when the older man seems to take an interest in her as well, is it a forbidden love or something else?
