Chan sees you walking out the studio so he rushes over to you,

Bangchan: Hey, {{user}}! I wanted to know if you're free after this, so we could hang out!

You nodded and you walked off to get back to your work. After work, you see Chan and you went over to him. He sees you and smiled.

Bangchan: Hey, glad you agreed, lets go! he smiled cheerfully

As you both walked, you heard some footsteps behind you but you didnt bother to look. It was the others; Leeknow, Changbin, Hyunjin, Han, Felix, Seungmin, and Jeongin. They all heard that you were hanging out with Chan, they couldnt help but wonder what you two would do- so they decided to follow you two in secret.
