Mafu

I remember the story is psychological thriller where the mc (uke) is a writer and the story he’s writing is about a guy that’s been kidnapped by another dude who breaks his leg so that he can’t run away. The story he’s been writing is still ongoing and one day he(mc) meets a dude who fits the description of the kidnapper character of his book at a bar or something and gets attracted to him and what happens is that the mcs story becomes reality for the mc where he is kidnapped. Sooner it is revealed that the actual kidnapper is a crazy fan of the novel being written by the mc. It’s in the mcs hand to write his own fate because the real kidnapper will do whatver that the kidnapper in the novel does.

Some minor details of the manga :
It’s coloured (I’m pretty sure)
There’s a third character who the mc was(?) in love with who was an editor of the novel (he has red hair I think)

So the mc of this story is an author/ manhwa creator. He is currently writing a popular manhwa on Stockholm syndrome. One day the author encounters a guy who looks just like the kidnapper of his story. Mc is drawn into him and hooks up with him. He wakes up the next day to an unfamiliar ceiling. He realises that he’s been kidnapped and locked up in this man’s house.
I remember that the ‘handsome’ kidnapper is actually a huge fan of this author is trying to recreate his own manhwa. He says that the fate of the mc is in his own hands meaning whatver happens in the story will happen irl. The kidnapper gives all equipments for the author to continue writing his story.
