Chuamong Tong Mon Episode 1

Cin is the breadwinner for her family: a younger brother, stepsister, and stepmother. Since she was very young, Cin's goals have been centred on being good, making merit, practicing the five precepts. She's late to work one day when she—along with Mate, a star she doesn't recognise—helps a woman deliver her baby in the street. But it's not the first time she's been late to work and she's fired on arrival. That same day, her boyfriend breaks up with her. After her desperate job search proves fruitless, her friend Nan gets her a job she isn't suited for: waiting at a party held by Mark, the CEO of an entertainment company and brother to Mate.
