T1, E1: In high school, Chang Ke-ai, the top student places a bet with Yang Tzu-hao, a study slacker that if they are admitted to the same university, she will carry his schoolbag for an entire year! As expected, Ke-ai is accepted by her first-choice college but the bet is called off as she has to give up her studies to pay off a family debt. Since then, their lives take a turn and are headed in a different direction. Ten years later, Tzu-hao has become Gorgeous Department Store's executive vice president while Ke-ai works as a street vendor who helps her mother sell clothes at a market. Will the two ever walk in the same direction again in life? Will they make up for their respective regret and become stronger when they're back in each other's life?
