A daughter of a rich and wealthy family who has never been exposed has come out to join the society (she is still a student). She was recruited to become a singer while working in a mask bar. She had no choice but to hide her dual identity. She had to hide her identity as a wealthy family in front of her boss and pretend to be a man in front of her classmates. She was tired in one word. Fortunately, her sharp-tongued childhood sweetheart would often find her to relax, and the two would entertain each other. . .
