Spoilers for Misery by Stephen King, and possibly giving away the ending of this Manwha.
From what I've looked into it seems that it's not the best ending, but the main character Paul (Main character here modeled after his experiences) escapes, and Annie (The person who Dohyuk's actions are modeled after here) dies.
I assume here the difference is he's going to somehow get in contact with red haired guy, and escapes. And somehow the psychopath dies.

have anyone read misery by stephen king? does it have a tragic ending?
