You're looking after your uncle's house when he's on his journey to travel around the world. You let some girls stay at the house to earn some money. As the story progresses, you'll make them fall in love with you or train them into sluts. The game will split into 3 routes depends on your choices:

Gentleman: You're a true gentleman who'll make all of them (or some of them) fall in love with you.
Pervert: You behave as a gentleman but at the same time, you spy on them and do pervert things but they don't know about that.
Jerk: You're a total jerk who'll make all of them (or some of them) turn into sluts.
