Fumihiko Matsumaru is an ordinary salaryman who has never had a girlfriend. One day he invites his colleague, Miss Tanaka, to a movie, but she doesn’t show up. Just as he’s about to discard the two tickets, a cute girl appears and begs him not to waste them. After the film and dinner, Matsumaru walks her home, only to discover that she lives in the same neighborhood. Unfortunately, her apartment catches fire hours later, leaving her without a place to stay. The young voice actress Aka Onda, a rookie in the industry, moves in with Matsumaru to keep her safe. The two begin a relationship that’s “more than friends but not yet lovers,” all while keeping their situation hidden from their employers.
