Background

In her backstory, Han Gyeoul was a normal kid. She often spent time with her brother who liked taking photographs, in order to not have to see the abusive environment at home. Her mother always rejected getting her photographs taken, this was because her face was always swollen after getting beaten up by her husband, Gyeoul and Wangguk's father. Despite getting regularly abused, she still had feelings for her husband and felt sorry for him. Her resolve didn't last too long as at one point, she committed suicide, leaving her children to find her dead body. Gyeoul was not old enough to understand, and was curious. This left Wangguk traumatized, and wishing that Gyeoul's brain represses that memory.

Her brother in anger had planned to kill their father but later refrained from doing so as he didn't want to take away Gyeoul's father too when she had already lost her mother at such a young age. He regretted this decision when one day, he came home from school to see his sister's swollen face as a result of getting beaten up in the same way their mother was by their father. This treatment led Gyeoul to start thinking that she should end up like her mother. In anger, her brother assaulted their father with a hammer. This led to him getting sentenced to 6 years in prison, leaving Gyeoul all alone.

While her brother was trying his hardest to survive in prison, Gyeoul didn't have anyone and had no idea how to take care of herself, much less going to visit her brother on her own. Her classmates in elementary school didn't believe her when she said that she had a family. This loneliness caused her mental condition to worsen, and she started developing an Obsessive Compulsive Disorder where she would hoard trash to fill the space left from her family.
