A 23-year old man who graduated Harvard flew back to his home country to sell fried goat meat in his self-made small stall, representing a conservative generation of youth. He went to a bar looking for a girl to settle his lust and found a drunken beauty.

They spent a wild night with each other, and the girl coldly and silently left in the morning in front of the guy’s face, leaving a small red stain on the bed sheet. After a few days, she forced him to marry her for 2 years by contract, and after the contract expires he’s free to do what he wants. She later revealed to him she’s the CEO of one of the biggest corporation in the country.
