Rabu Hina (2000)

When Keitaro was a child, he was friends with a little girl. When the girl had to move away, the two made a promise to meet each other at Tokyo University when they grew up. Years later, Keitaro has failed his entrance exam twice, and his parents refuse to support him any longer. His grandmother gives him refuge and employment as caretaker of her inn, which just happens to serve as a female dormitory. The eclectic group of tenants tease, annoy and berate him to no end. Still, Keitaro won't ever give up his promise to meet his childhood friend again, even though he can't remember her name.
