The witch (her on the right) needs to have a baby with him to secure her grip on the family fortune, but she can't. So she pays a large sum of money to one of the other girls who work at the dealership to get pregnant by her husband. He knows nothing about it. The hired baby maker slips him some powerful aphrodisiac so he will jump her. But he passes out and while he is out she gets a call that her father has died and rushes off to meet the family. Fortunately for us, Taengmo just happens to be her roommate so when the guy wakes up, ready to go from the magical Chinese aphrodisiac, he jumps Taengmo. The story deteriorates from there with all kinds of bitter fueding and such. Eventually, we presume, he ends up with Taengmo, the only real hottie in the show.
