Hao Wen excels in both work and relationships, living his life surrounded by beautiful women. One day, he quits his job after an argument with his supervisor. He then travels to the beautiful beach of Kenting National Park, Taiwan, enjoying his life surfing and changing his partner in bed every day. However, the arrival of a little girl who claims to be his daughter turns his world completely upside down.

Energetic, masculine and tall, 26-year-old Wen Hu is deemed as Mr. Perfect. What his admirers don`t know is that the handsome young man is hiding a secret: he suffers from erectile dysfunction. He must now find a way to overcome his problem within 30 days. It is because he will need to propose to his girlfriend soon, as his mother is forcing him to marry her as soon as possible so that he can offset the bad curse that she believes is the reason she has fallen ill.
