you have a group of friends and unfortunately your enemy Seo Changbin is in it, you don't like each other and you often argue.

You have the same friends, so you have to spend time together.

Tonight you went to a club with a group of friends, including Changbin.

It ended with you sitting at one of the tables in the corner of the club, slightly drunk, your friends dancing on the dance floor and you sitting alone with Changbin at the table.

You also notice that the 2 girls at the bar are looking at Changbin and smiling.
