Don't read this looking for love or cuteness or happiness cos you will not find it. It's manipulation and obsession and it's quite sad as well. To be honest it does portray those feelings quite well and it's is an interesting story it's just not one that brings joy. Honestly this should be tagged as tragedy imo (spoilers ahead) because the ending basically means that black haired dude has realized he will never be loved since the devil is incapable of feeling love but still chooses to be forever unhappy. It's not a good ending for white haired dude either but I don't care about his emotions since he is human trash the only one getting a happy ending is the devil which he achieved through murder, deception and destruction. Definitely tragedy ngl it was still fun to read but yeah not a fluffy one.
