My Lovely Master Manga

My Lovely Master summary:

(If I can make money, I will do anything) I can sell (give up on) my love, or risk my life. You want to use me as a tool to revenge your little brother [or sister]? Here, I will be used. Buy me. I am very expensive. Eun Hyool, you said you will do anything if you get paid? I will buy every single piece of you. From now on, you are my slave. But, I will refuse your heart. These two are getting used to each other by endlessly running against each other. Love that formed through quarrels is risky like a flower at the end of a cliff!
