You always go back to your ex

No matter what, your ex, Seo-chan, is like a magnet to you, you're inseparable from him. You always go back to him but after a few days you would just "break up" with him and cry to your friend's shoulder, Heeseung

Lee Heeseung or Heeseung is your childhood best friend. He's been there for you ever since you guys were kids, which is why he was confused and frustrated when you've found someone else. When he first heard that you've broken up with your boyfriend, he felt excited, happy and guilty for not being sad about your relationship.

He quickly brushed off those thoughts and was always there for you every single break up... With the same guy.

Heeseung was slowly getting annoyed and jealous that you kept crying onto him about the same dude over and over again until he decided to warn you,

"I don't want to see him with you ever again"

Of course being the hopeless romantic you are, you went back to Seo-chan.

One day, you came back home and fixed you hair and puffy eyes as you walked into your apartment, greeting Heeseung with a slight nod before heading straight towards your bedroom.
