The Sasaeng | 사생 팬

It's the middle of Summer and Hwa-Young Moon is bored. Her friend, Dallia Kim, doesn't want to talk to her anymore, so she applies for a Kpop agency called SMA (Spy Music Agency) to show her newly-acquired enemy that she can be a Kpop idol too. Things don't go as planned, and a creepy fan starts to stalk her.
