All is well in Ong Seongwoo’s life. His group, Wanna One, might have disbanded but the fans haven’t left. He’s missing the performances, concerts, and the members, but thankfully he has projects lined up to keep him busy. He wishes for life to be as happy as it is for a very long time. But life has different plans. He’s filming in an escape room for his own reality show one night when cosplayers suddenly turn up and ruin the show. He tried to approach them only to realize that there are two different groups and they’re fighting. What’s worse is they aren't fighting with punches and kicks… It looks like they’re fighting with their fangs and claws! What’s happening? Did someone poison his tteokbeokki that morning and he’s somehow hallucinating all of this or is this all true and these people are just excellent actors with out of this world props?Or, perhaps, this is something truly out of this world... Because who bleeds and dies on a show without the help of CG? Right? Not just someone but a lot of someones ended up dead in this chaotic freak show that overran his. Why is no one calling the police?!
