Happily ever after comes with a curfew!

When bubbly eleventh-grader Eimi Yamashita finds out that her parents are relocating for work, she decides to strike out on her own and move into a dormitory for girls. Little does Eimi suspect the exciting romantic adventures that await her there!

Eimi's going home for the holidays--but she's only been to her parents' new house once! Shimonuki is all set to accompany her, but a family emergency keeps him in town. Eimi doesn't want to take the train alone, so she drags Wanibuchi with her. They spend the holidays traveling across the country and through Wanibuchi's past. Will his revelations bring them together, or ruin any chance of a happy ending?
