As far as I remember- Merry's Dad is different from the hyung(I actually forgot his name already wtf) the hyung's dad was friends of merry's dad, but merry's dad died and I think it was because of that bitchass witch we all hate, and then the Hyung's dad started to like help/take care of merry's mom, so like the witch thought she'd get all the men, reason why she hates her so much lol... Therefore there's no blood relation here. They're basically like childhood friends but I guess merry treats him like a big brother cause it was the only person who looked after him since small. He's so innocent that he probably doesn't know it sounds a little weird LMAO.
God knows who is Meili's father.
does this have incest????
