Seo Changbin ⁻ ⁽¹⁵⁾

Changbin and you broke up about three months ago. Although he kept contacting you on Instagram, it got to the point where you had to block him.

He stopped sending you messages, but the truth is that he didn't forget you and only lived with what your friends told him about you.

You arrived at your best friend's party, and the first person you saw was Changbin. Just as you were about to turn around, he spoke to you.

—"I'm not the person you used to know."
