DEAR. DOOR (Comic) Vol. 4

Volume 4 of the DEAR. DOOR comic opens with the demon king Cain in a fury, tearing through lesser demons one after another. The cause is a betrayal: Sid, the general he trusted most, has turned against him. Cain now has to assume that Sid is feeding information to Satan, his rival.

That threat puts Kyungjoon, the human Cain calls his door, in danger. To keep him safe, Cain decides the only option is to leave him and stay away.

Cain did not account for how badly Kyungjoon wants to see him again. The longing grows strong enough that Kyungjoon considers throwing himself from a height. He is certain Cain will appear the moment he is truly needed. Whether the demon king will actually be there to catch him is the question this volume is built around.
