When painter Youngsoo (Kim Joohyuk) learns that his girlfriend, Minjung (Lee Yooyoung), was recently seen having drinks with another man, he can’t help but question her about it. It doesn’t go well and they part on bad terms. The next day, Youngsoo tries to find her, but can’t. As he wanders and frets, Minjung has a series of encounters with other men. But to them it seems she’s not herself.

Featuring a supporting cast of Hong regular's Yourself and Yours is a delightful comic mystery of mistaken identity, he-said she-said, and excessive drinking. As the confusion builds, Hong examines the roles we play and questions what it means to know someone and to be known.
