In both middle school and high school, Kawashima hadn't had any luck with girls, but today he's had a miracle encounter! In the apartment building he moved to, there was a high school girl living right next to him and in addition to that, she's living alone! This situation that any man will admire has Kawashima hyped up! However, there was also something odd about it: She likes to drink beer. What is her identity? It's a slightly ecchi high school girl comedy!
