But the landlord, taking advantage of Hana's words "I'll do anything," makes her help with his sexual urges. Handjob, pussy licking, fellatio. It escalates more and more, and one day, he finally forces her to have creampie sex. Hana, as she indulges in the landlord's perverted hobbies, learns the joy of being a woman and falls into sexual slavery.
