an ji ho

Yoona is a master barista who dreams of opening her own cozy coffee shop. Ahn Ji-ho, a financial genius, buys a building to open a chain "coffee conveyor" with robot baristas. They rent the same space due to a real estate agent's mistake. Neither wants to give in. The judge orders a "probationary period": they work together for 30 days. Whoever brings in the most profit stays. Yoona brews by hand, pouring her heart into it, but she has few customers (it's expensive and takes a long time). Ji-ho installs a vending machine, selling cheap Americanos by the ton, but customers complain about the "plastic" taste. To sabotage each other, they begin "slipping" strange ingredients. Yoona adds cinnamon to his vending machine (he's allergic), and he turns off her lights during a date with a regular customer. One night, they are left alone to count the proceeds. Ji-ho admits he hates coffee because, as a child, he smelled of it in the hospital where his mother was hospitalized. Yoona makes him a "decaf latte" with caramel and milk.
