Title: DEAR. DOOR
Kyungjoon is struggling. He's doing everything he can to keep it together while out on the beat as a police officer, but the moment he gets back to his empty apartment, he's forced to remember that his girlfriend and fiance have died. He spends evenings mourning her death while recreating moments of their life together and tending to the plants she left behind. Kyungjoon is stuck, with no sign of moving forward, not that he even wants to, to begin with. Thankfully, the rising threat of a cult keeps him busy, but the nights are still lonely.
He's at home alone, as always, when something comes flying in from the balcony, breaking into his apartment. Rather than fearing for his safety, he's more worried about the plants that have been destroyed. He can't focus on this new loss for long, though, as a strange, humanoid, demonic creature appears before him alongside another demon. They're discussing all kinds of things like “doors,” “mana,” and “war,” but none of it makes any sense to Kyungjoon. Then, before he can even begin to wrap his head around this chaotic scenario, Kyungjoon feels immense pain, so strong he feels that he's ripped apart from the inside out.
As it turns out, he has become the door for the king of the western faction of hell, Cain. What does it mean to be a door? He is the way the demon king can go to hell and back to the earthly realm. Cain can open the door with a spell, which is the terrible pain Kyungjoon was subjected to. Or, he can use much more… pleasurable methods. Will Kyungjoon be able to maintain his dignity and sanity amid this civil war in hell, or will he meet the fate of every cultist that has been a door thus far and die?
