So what had happened was you were looking for Seungmin to show him a edit you found of him. You walked in the room “Se-…” you were about to call his name but what you just saw you closed the door immediately and ran back to your room looking yourself in there. You had just witnessed what you think to be Hyunjin and Seungmin kissing. You just saw lips on lips. That’s all you saw. But the was you shut the door so quick and ran might have caused a commotion
