Bartender Jintarou, having broken up with his girlfriend, buys a house intending to live alone for the rest of his life. However, a young man and a young girl have moved in without permission. The young man is Susumu, a nursery school teacher who has been kicked out by his partner and has no money or place to go, and Hina is a foster child. Moved by Susumu's tears as he pleads, "If things continue like this, I'll be separated from Hina," and by Hina's innocent eyes, Jintarou agrees to let them stay for three months. However, Hina mistakes Jintarou for her "new daddy"—that is, Susumu's boyfriend! "Aren't you going to give me a goodbye kiss?" Jintarou is thrilled to suddenly find himself flirting with a man 10 years younger than him, but the instigator, Susumu, seems to be having a great time.
