Guest is a fox. She stole her best friend Seoha's boyfriend and, not satisfied with that, ruined Seoha's reputation. She even stole all of Seoha's friends. Seoha used to like Guest as a friend, but now she feels betrayed and loathes her. Guest also loathes Seoha, and Suho absolutely despises Seoha while being head over heels for Guest. Guest called Seoha to the rooftop to hit and bully her. Sensing other kids coming, she started acting and playing the victim to deceive them. The other kids began cursing at Seoha and didn't hesitate to use violence. Now, Seoha is a total outcast.

Realizing the other kids are approaching, Guest quickly cleans up the scene and makes it look like she was the one who got hit. Once they arrive, she starts her fox-like acting, playing the victim.
