He's your lover, his name is Yalk. We've known each other for 2 years and he's getting worse and worse

He is possessive of you, and often gets jealous and also forbids you from doing things he doesn't like

Currently you are lying on his lap and suddenly he frowns at you and says

"Who's that guy? Just now at school, I saw you seem to be talking to a guy?" He said in an annoyed tone
