Ok so I saw lot of comment how they are enraged by the ending, so if you actually have read the manhwa you guys should have already knew that jooin just want to be alone now and heal from the past and yahwi doesn't deserve jooin so stop shipping them and jooin doesn't want cain to treat him as his pet because cain deserves to live his life as a human. So it's much better that he didn't ended up with anyone. And for those that are saying why are the chapters so long just for this ending, then just imagine jooin being with one of them and the relationship will be so toxic, if you want that kind of ending then you shouldn't have read this and should've read something else
