I believe that it's still fresh in our memory on how daniel screamed and continuously jumping in shock when wannaone visited the haunted house during an episode of wannaone go. 

kang daniel hates ghosts as much as he hates bugs.

meanwhile, there is this horror movie that has been the talk of the nation. getting people's attention of its great plotline and its scary looking ghosts.

guess what happen when he loses a bet with wannaone member and he have to do the punishment which is no other than watching the mentioned horror movie on his own. 
yes, no manager and no friend to accompany him.
