I liked how masumi is careful around yuki as to not accidentally hurt him or give him some bad experiences. I also like how before they date, when yuki said no, he immediacy backed off and after the sudden kiss (in yuki's house), he apologised for his action. So far, I liked the couple, I wished we get to see more of cute masumi (like when he get all clingy to yuki when he's drunk). I would love it more, if the sex in the last chapter dia contains those no while they're doing it, it ruined the experience a little bit for me. Apart from that, this story is fine.
Iyaya Iyaya mo Suki no Uchi?
