Synopsis

Chaerin participates in a commercial shoot and receives her first earnings, which she surprisingly wishes to invest in stocks. Her father, concerned about the risk, sets up a safe stock account while also playfully threatening to close it if she loses all the money. Concurrently, the father has been experiencing a string of good fortune, including his dissertation approval, and has noticed odd physical changes, such as a sudden growth spurt, leading him to suspect that he's undergoing some unusual transformation and links it to his daughter's influence.
