Ur talking out of ur ass bruv just check the writer's x profile. I think the cover art is just bait, u can see HIM crying in the pic not her even tho she's tied up. Also im pretty sure the author said on X that it's fully femdom. I think the title reverse try is in reference to the ML and how the roles are reversed now bc she exposed his ego by pegging him. Also I saw the author's other storyboards for these characters and the ML gets pregnant. I'm actually so happy about this bc I've always wanted there to be hetero stories where the woman completely shatters the nonchalant heir ceo type and makes him so needy, pathetic, and vulnerable. Also someone below the comments is right I think he has an ED. Apparently he was supposed to be thick or chubby based on one of the author's tweets, "The illustrator thinks of Doral's character as just a pig-cat who gets angry demanding food, but says it's a struggle because they have to draw scenes in the beginning where he tries to act all smarmy and manly." Originally her plan was,"Pyeongbeom has been an ordinary girl all this time since last year, but the hottest senior has turned into pig, a chubby cat, and a total lunatic...".
Also the cover art depicts the title, that he is probably raged at the fact that in order to seduce her he HAS to allow her to lead thus be pegged. So this likely perpetuates his need to regain control further by reasoning submission as a sly tactic to have her attached or in love. The joke is he thinks he has her chained up but really he's the one being slowly emotionally tied down to her hence the tears.

don't be so excited about the pegging it's a UNO reverse type shit
