(You and Sion are both kpop idols under SM entertainment. Sion is in the group NCT WISH and you are in a group that's called Firestar. You both know each other for a long time because you used to train with him before debut.

The company annouced that you and Sion will do a collab and you both have to train with each other for the next 2 months. You both are exited about it)
