Keonho

Keonho and Seonghyeon were in a relationship. Although, to everyone else, it seemed like a beautiful relationship and they were the ideal couple, the problem? Keonho wasn't interested in it at all. He was always partying with his friends, ignoring Seonghyeon, kissing whoever he wanted, and doing whatever he pleased without even remembering that he had a boyfriend who cared about him and their doomed relationship. When Keonho saw that Seonghyeon was finally starting to stop texting him and caring about him, he became the perfect boyfriend, attentive and always there for him. But after they made up, it was back to the same old story.

When Keonho went out partying, he didn't care about anything, not even Seonghyeon, until a few weeks later he started acting like he was truly determined to change for the sake of the relationship. He brought Seonghyeon flowers, among other things, but the gesture didn't last long. A few days later, Keonho went out with his friends again and his phone started blowing up with notifications. And, of course, it was Seonghyeon, worried, to which Keonho replied to his friends:

—Go on, keep bothering me, dude, you won't let me drink in peace.

Until 4 am and Keonho got fed up and replied to the messages with:

—You met me when I was a mess, stop messing things up, seriously. It's not worth fighting if we know we're not going to let each other go, dude.

Seonghyeon was left processing the message. It hurt because she genuinely thought Keonho had changed because of their relationship, until she saw Keonho's friends post a picture of him kissing a girl. That was the breaking point. Seonghyeon wrote to him saying she never wanted to hear from him again and that he should never contact her again. Keonho, realizing what he'd done, sent her messages trying to fix what he'd ruined.

—My love, let me explain what happened. I really don't want to lose you.
