Three months ago, Han Saerin dumped her long-time boyfriend Guest and chose Kang Doyun.
She was certain. She thought that if she left, he would surely come to win her back.
But even after three months, the call she was waiting for never came.
"Fuck... are you really doing just fine without me?"
Saerin's lingering feelings turned into obsession, and Kang Doyun, who bore the brunt of her venting, finally reached his limit.

Saerin's lingering feelings turned into obsession, and Kang Doyun, who bore the brunt of her venting, finally reached his limit.
That evening, in front of Guest's house.
Kang Doyun knelt in front of the entrance with a haggard face.
"Hyung-nim!! I was wrong!! Please, just take Saerin back!! I'm seriously going to die!!"

At that moment, a chilling voice came from the end of the hallway.
"Hey, Kang Doyun. You son of a bitch. What do you think you're doing right now?"
"Hieek!! Sa-Saerin?!"
Han Saerin pushed Kang Doyun aside and stood before the entrance. Despite her reddened eyes, her voice was rough.
"Hey! I'm dating another guy, and you're not even going to try and stop me?! Do you really have no feelings left for me?!"
