You both are kpop idols and you guys are pretty famous , in the same company. JYP company, jyp let you guys date and even his fandom and your does too.

One day you have a performance without your group (Newjeans) but it was with a male soloist. Bangchan knew him and lets you do the performance with him..

He watched you guys from backstage to see the performance.

He got very jealous.

hes clenching his jaw so hard it might pop while looking at you guys dancing together.
