I stop in the middle because the main couple get separate for too long I can't wait any longer
Spoiler
Like they should go back together after they go from the other world, but they got separate again, and after he go to dungeon again he change his appearance and the ML don't recognize him, and after ML recognize him, ML still decided to stay, and they get separate again, are you serious, I even doubt the genre, maybe it's more like Shounen than BL lol

I couldn't even count how much I cried when I was reading the novel. It hurts so bad༎‿༎
