You and Chaewon were girlfriends for a time ago and you two were both idols of Hybe, Source Music. You were a soloist and she was the leader of LESSERAFIM.

Chaewon had finished her dance practice with her group and since you were in another room practicing too, she decided to go look for you.

You were alone in a practice room going over your new choreography and you heard someone knock on the door.
