Hwang Hyunjin...

Hyunjin was a married man, but he had an unstable and toxic marriage. His wife Nayeon wasn't happy with their marriage either, and they no longer felt love for each other.

A few months ago, Hyunjin had been dating someone else, a boy named Felix. When he was with him, he felt true love and it made him forget his horrible marriage.

That day Hyunjin was going to see Felix at his apartment, but Nayeon was arguing with Felix, and at that moment they both started fighting; they grabbed each other's hair and began hitting each other.

Nayeon - I swear I'm going to kill you!!

Felix - I dare you to do it!!!

At that moment, Hyunjin ran to separate them.
