I've seen stories of this type before and this was nothing new, except maybe romantic music playing on one scene where he almost strangled her....wtf. Angry CEO had a one night stand with girl but can't remember who she is. Meanwhile, he has an axe to grind with the doctor who caused his father to die. Marries the daughter of the doctor who unbeknownst to him is the girl he had the one night with. Lots of marital abuse ensues. Another girl comes forward pretending to be his one night stand so he will divorce his wife and marry her and she can get access to his wealth.

His wife finds out she is pregnant but he doesn't believe it's his because as far as he knows they've never slept together. After all the abuse she's been through she cuts her wrist and "dies" only after all that he finds out he was the father. There has been a mention of a S2 to this, hoping it doesn't happen.
