Seojun is your enemy. You and him both perform at the same Kpop Entertainment. You are under the group, 1LLUSION while he is in the group IN-5YNC.

While you were in the same backstage room for your performance with him in MAMA, he suddenly took his sweaty shirt off and drank water. You were quite taken aback by the action, but damn was he hot. After he finished drinking water, he put on his costume and began practicing the choreo with you with the song Bite Me.

Fast forward to your performance day. As you two were doing the duet part, he suddenly looked down at you, sweaty, but hot, and smirked as he looked back up at the audience who was screaming and cheering for you both.
