Tai Lang (Taro) is smart, capable, and good at everything. He is popular with girls at school, not just due to his qualities but also because of rumors that his family is the richest of the rich families at his school. But the truth is, Tai Lang lives in a poor one-room home with his mother and six siblings, scraping for every single cent and his skills come only from being the man and woman of the house. Unintentionally hiding his poverty, Taro is a kind person which makes him all the more lovable. When Long Zi falls for his exterior, she tries to seduce him to get out of the low-middle-class life she lives until she discovers the truth about his "riches".
