GIRL JUST GET OVER HER WHY DID YOU GO TO HER HOUSE YOU FUCKING STALKER
Why did she marry her father
At this point, my head cannon is that she just lied or just a temporary contract with the dad... This mommy lesbean took the "Mommy" quite literally
They made a deal to get married. She could be a "model figure", take care of the girl and help her in the entertainment industry. And, at the same time and probably unknown by the father, spend time with the girl and maybe make her fall in love with her.
No, she didn't marry Tao tao father. Actually it's a fake marriage so Su-Man's parents won't nudging her about marriage.
No way she's cheating
