Bonjour encore !

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?

After taking over Ke-ai's debt, Tzu-hao demands Ke-ai to work at the department store. On the first day, Ke-ai is isolated and mocked by her coworkers. She is also forced to buy a blouse damaged by a difficult customer. Under Tzu-hao's provocation and Hsiao-kang's encouragement, Ke-ai conducts a live stream to promote the clothes. She manages to increase the sales but things aren't simple as she thinks. The second-floor supervisor, Wu Hsiang-yin intercepts when she finds out about the live stream. A battle between the top student and an old hag is about to begin.

Ke-ai takes on Mr. Jiang's challenge to hit five million sales a month despite knowing that it's an impossible mission. At that juncture, the board of directors' strenuous opposition and the conflict among the promoters almost causes Yin-yin, the store manager to suffer a miscarriage. On the other hand, the chairman of Daily Market, Mr. Tiger intends to increase the rent and subsequently trigger the battle between the market and triad. The duo develops unique feelings for each other after being confronted by challenges that come one after another.

Tzu-hao and Ke-ai work hand in hand to hit five million sales. All the promoters deliberately go against Ke-ai after feeling dissatisfied with her appointment as the acting store manager and the second-floor supervisor. On the other hand, Tzu-hao gets jealous when Hsiao-kang shows his concern for Ke-ai. Tzu-hao stands up Chien Chen-yi, the heir of Jubang Bank numerous times. As a result, an irritated Chen-yi shows up at the department store and she is immediately smitten with Ke-ai who is thoughtful and adorable. Besides Hsiao-kang, Tzu-hao has to compete with Chen-yi who behaves like a lesbian to win Ke-ai over. The triangle love has now become an unprecedented rectangle love.
