The Sadist Training Plan Condition - No way… you’re going to lick me there?
Ongoing | Mariko sawamura | 2019 released
Yanagi Yuzuru. Both my favorite names in one! He was becoming a Sadist for her sake. Akari didn't pay attention and they ended up dating because he found her request interesting. Weird fellow. He's possessive but not to the extreme. He gets jealous very easily.
