Becoming a Billionaire

Choi Seok-bong believes he is the son of a billionaire that had a one-night stand with his mother. While working as a bellboy at a luxury hotel, Seok-bong practices the qualities he thinks a billionaire's heir would have; all these efforts are for the day he meets his birth father. But one day, Seok-bong is diagnosed with breast cancer, which only has a 50 percent survival rate. Seok-bong doesn't have enough money for treatments, and finds it absolutely ridiculous that a billionaire's heir would die because he has no money. Finding his biological father may be Seok-bong's only hope, so he turns to Lee Shin-mi, the heiress of Ohsung Group and a notorious penny-pincher, for help.
