Kaseifu ★ Koi wa Keiyaku Kara

You're an employee living in a large mansion; and you've become its housekeeper.
Alongside you living at the mansion - there are also some lodgers there, who get to live there for free. They are all rather mysterious guys, who belong in the household for certain circumstances.

You are issued numerous instructions from them - as they mercilessly demand task after task from you.

"Tonight, come to my room."

"You should wash my back."

.....In spite of being bound to a relationship via a contract, will your presence alter the bonds of the family there - whilst your own life has turned into a mess?
