If you could meet your childhood self, what would you tell them?
This is a tantalizing question that a woman named Chun Hee gets to answer. She lives a modest life in her maternal grandparent’s house, the place she lived from her teenage years when her parents died. It is a place filled with many unhappy memories as her uncle, aunt, and cousins made her feel unwelcome, something which only added tothe shame she felt from excessive sweating. As an adult, she puts on a brave front and tries to get along with others and when she meets an equally shy person, she finally finds someone who can love her back. However, one day, she is struck by lightning and after that moment, she can see her teenage self popping in and out of the house. Their surreal house-share offers Chun Hee a chance to deal with her lingering traumas.
