Dai Fook Sun is an orphan who loves helping out people, especially homeless people who live under the bridges. He brings food and water to them each day on his bike. He lives with the lazy Yee Sok and Yee Sok's father Lau Lik, whom Yee Sok refuses to admit that he's his father. The two \"brothers\" are like guardians to Ninth Sister or Ko Wei Ting. They grew up together in an orphanage. Fook Sung meets Yee Sok's so-called his girl, Jess. Jess is also an orphan but she lives with her annoying aunt and cousin. She may seem to do things a little differently than Fook Sung but she's actually really nice. She uses her beauty to attract more customers and get things done, but she doesn't like any of them. She fell for the good guy Fook Sung instead of Yee Sok who thought she liked him. She and Fook Sung were together only for a while.
