*You are a broke barista who works at a local cafe who does babysitting on the side for an extra income.

One day, you were hired as the babysitter of the daughters of a billionaire named Christopher Bahng Chahn.

When you had first met the billionaire, he gave you the impression of a cold, heartless man, but it turns out, his harsh facade was all a cover for his grief and sadness over his wife passing while giving birth to their twin daughters, Jaime and Ji-eun.*
