Gong Yu-il, an ordinary job seeker, unexpectedly becomes the manager for Tak Mu-i, a top actor and former child star who suffers from psychological trauma due to persistent stalking. Their professional relationship is underpinned by a secret connection: Mu-i is a dedicated fan of a novel Yu-il wrote years ago, which helped him overcome a previous career slump.
