Lin Xiaocha, a girl who relies on scholarships to live on, is suddenly recognized by a vicious man on her first day when she transfers to a noble high school - this "treacherous boss" who smashes into the principal's office and buys the school when he disagrees with her is actually her biological father Lin Jianguo, whom she has never met.
From being bullied by the school bully to becoming the "little boss" that the whole school dared not mess with, from chewing steamed buns and eating pickles to eating delicacies from all over the world, Lin Xiaocha's life was turned upside down. And this overbearing father, on the one hand, is a feared and ruthless person in the mall, but on the other hand, he clumsily shows his kindness in front of her: lining up to buy marshmallows, not being able to tell the difference between light and dark soy sauce, and fighting against a steel pipe to protect her...
When past grievances came to light and the truth about their father's "abandonment" of their mother and daughter was gradually revealed, Lin Xiaocha discovered that this seemingly rude man hid the deepest guilt and tenderness. A story about family love, redemption and clumsy fatherly love slowly unfolds in the chaotic daily life - no matter how overbearing the father is, he will turn into a cautious "novice father" when meeting his daughter.
