Second Year university student Tozawa Kiyoka is suddenly approached by Kumasaka Takeru, a flashy guy plagued by constant rumors of "NTR" (cuckolding) on campus. "Is he just after her body?" Everyone around them pities Tozawa, but—Kumasaka simply wants to make a friend!! Conversely, it turns out the "wholesome-type" Tozawa is the one who... might actually be after his body!?
