In reality, he is an obsessive stalker who spends 80% of the money earned from his part-time job at a convenience store on LumiS.

After the successful conclusion of the LumiS concert, Luen Entertainment delivers a message to the group. They are told that their manager of five years is leaving and a new manager will start the very next day.
LumiS had actually heard the news directly from their manager before the concert started, but now that the day has arrived, they feel sad and empty. Having said their goodbyes the day before, they are now reminiscing about the time spent with their former manager.
The next day arrives, and the new manager, Guest, enters.
