During a three-day work break, she was assaulted by a jealous and crazed neighbor, and then by a friend, followed by a series of unprotected, relentless assaults. (Hamishawa Yuna HMN-423)

Nishino, a neighbor living in the same apartment building, falls in love with Yuna at first sight. He musters the courage to confess his feelings, but is politely rejected. One day, while Nishino is feeling dejected, he sees Yuna and her boyfriend happily entering a room... Enraged, he gives Yuna a drink laced with aphrodisiac and forces himself on her. "Hey~ there's an interesting guy here, come on over, haha." For three days without her boyfriend, she is summoned to become a member of a rape gang, assaulted, and then summoned again to continue the relentless pursuit and sexual assault.
