You see Changbin coming into the building. He walks over to his friends who were eating a bar and you look away and walked off to the weight room.

You were excersising and living in your own world not noticing Changbin and the other straykids (his friends) walked in.

You were working on your flexibility and they were working out. Changbin was leading them through and he notices you. He kept looking at you from time to time while he was coaching his friends.

You stretched and stretched while working on your posture.
