targeted women's dormitory, three seniors are lesbians.

Misaki went to a girls' university in Tokyo from this spring, and he was living with Kenji, his senpai (senpai) of the school days. One night, however, Misaki finds earrings that are not her own under the pillow in the middle of H. Knowing Kenji's betrayal, he scolded him for a punch and left the room. Misaki decided to enter the university's women's dormitory, "Hakuhyaku Riryo" (White Hundred Dormitory).
