A hairdresser from Busan ambitiously opens a one-person hair salon in Seoul. She busily prepares to greet customers, but no one visits but a mosquito.

On the third day of Momo Salon, Heni finally greets Chang Gyun as her first customer, who asks for a hairstyle appropriate for a job interview.

Thanks to successful delivery business, Momo Salon is now packed with customers and becomes a place for everyone in the neighbourhood to get together.
