A story of laughter and romance between two polar opposites as a penny-pincher crosses paths with a spendthrift. Liu Jia Yin goes bankrupt after breaking up with her wealthy boyfriend. Caught in a bind and forced to pay of her debts, she sells of all of her belongings. Wang Ji Wei was born frugal and goes to extremes just to save money. An accidental meeting forces them to live under one roof and reassess their disparaging outlooks when it comes to money and love.

To shed his "rich kid" label, Yang Doudou founds software company 3Y with Ma Fuyun and Lin Dawei.

Meanwhile, Oscar Wang, the stingy owner of the park's restaurant, becomes part of their circle. As they chase their dreams, Yang Doudou falls into a complicated romance with Meister's fashion director An Min, while Ma Fuyun harbors unrequited love for Meister employee Deng Sha. Thanks to a string of quirky apps, 3Y's business picks up, and Yu Ya realizes her feelings for Ma Fuyun go beyond friendship. Through one hilarious farce after another, 3Y marches toward success — yet the young men's and women's relationships grow ever more tangled.
