Solar and Moonbyul decide to get back to being roommates despite their fame and money.

What the oldest one never considered was the stress to hear every action that happened on her best friend's room. Practically every night.

Solar's boyfriend starts feeling uncomfortable and insecure because he doesn't cause in her that kind of reaction he hears coming from the other bedroom.

The singer tells her friend about how awkward things are and about her talk to her boyfriend.

Moonbyul promises to stop bringing her dates. But soon, she feels bothered by the couple's lack of chemistry and she gets tempted to try her luck.
