From Fairgame:
In both middle school and high school, Kawashima hadn't had any luck with girls, but this is a day that a miracle encounter came to him! Apartment where he moved, there were a high school girl living in his neighbor and in addition to that, she is living alone! In a situation that any man will admire, Kawashima's tension is hyped up. However, there was also a odd part to it, like she likes to drink beer. What is her identity? It's a little bit ecchi JK comedy!
