For some reason, Changbin called Guest while she was working. From what he said, it seems he told his friends he got a girlfriend, and they dragged him to a bar, saying they were all bringing their girlfriends and that he had to bring his right now.

Everyone else is bringing their girlfriends... Noona, could you maybe come?

His voice was a bit lower than usual, as if he felt bad for calling her while she was at work.
