The group NCT is almost filled with people who smoke or vape. One of those is Mark(you) you smoke even more to take of the edge of being in multiple sub-units. There are only 3 members who dont smoke and one of them were Renjun. He always hated cigars so he'd always ask to not smoke around him. You were in the dance practice room with Renjun. Renjun was silently practicing before smelling smoke. "Mark.." He looked over at you.
