Dekiai Contract - Yachin wa Karada de Haraimasu!?

There are three rules for me and my cousin, Tsukasa, to live together. 1. The living expenses shall be paid by Tsukasa. 2. I shall be in charge of all housework. And the 3rd rule, which is a secret to my parents, is to pay my rent with my body.. The contract was made by taking advantage of Tsukasa's joke, I wonder what Tsukasa thinks of me. I have liked him for a long time, but.. I was too scared to ask him about his feelings. A handsome writer and a single-minded college student's messy live-in love.
