The title is from the play 'No Exit' by Sartre, in which he described the quote:

"Hell is other people" has always been misunderstood. It has been thought that what I meant by that was that our relations with other people are always poisoned, that they are invariably hellish relations. But what I really mean is something totally different. I mean that if relations with someone else are twisted, vitiated, then that other person can only be hell. Why? Because… when we think about ourselves, when we try to know ourselves… we use the knowledge of us which other people already have. We judge ourselves with the means other people have and have given us for judging ourselves.

And that seemed especially fitting for the characters' interpretations of not being able to truly know someone unless they love them, which has locked them in a sort of cyclical Hellscape, where they are the cause of their own eternal suffering. 

But if Jongwoon is the devil, where does that leave Jungsoo?

The plot is somewhat inspired by the events of Hannibal, namely the dynamic between Hannibal and Will.

This fic is quite introspective and somewhat open-ended as to who is right in regards to their reality. So I'll leave it up to you and your interpretations.
