Dear mangago reader..could you help me to find this yaoi manga name..there is a kouhai living together with his senpai..the kouhai really admires his senpai but the senpai never treat him kindly..he was treated like a slave but the kouhai never complain..one day his senpai bring a woman to their house and........cant remember what happened after that ..
