Daehyun asked fans to refrain from coming to their dorms.
He recently tweeted, "Please don't come to our dorm. We are okay with it, but it can bother others. I ask sincerely." It looks like he's talking about the sasaengs who camp out in front of their dorms all day and night. He's incredibly polite about the situation, but it sounds like he's had enough of fans following them everywhere.
Hopefully this gets the message across.
