Name of a Manhwa

Hey wasn't there a manhwa in which ml is a fictional character of mc's novel or something like that and he was very villanious and the mc was a cripple. The ml has to travel to real world using trains where every character can take a ticket to the real world ( and maybe when mc dies all characters made by him come to see him ) . Mc tries to kill him by writing another novel of his death.
It was a shounen -ai maybe. Can you tell me what its name was?
