I did not expect anyone to be the same as me, ununseti! Platinum End is indeed a disappointment.
The drama, actually, slightly reminded me of the Death Note which included humanity emotions and fate, but was too edgy to read.
Then, Nanoka no Kare, Koi to Uso, and circles that have the concept of brashness in a relationship. It might be different, but it's too depressed. I'm not quite picky, but there should be something that can make you endure to like it and not just show each other less teachings so that everyone ends up being victimized by their own ignorance. I also don't like kind of Kurosaki-kun no Iinari ni Nante Iranai with strong misogyny and shows how love can be something stupid to blind them.
From these two fields, I don't like stories that develop with excitement for the sake of tension. Or the worse, because of it's popularity and their addictive bastard characters. A fanatical urge for something too dreamy.
The recycling in Isekai which also made me never interested in trying them. A trend, and shoujo follow up too --well, then, I don't think it makes any difference if you read a Harlequin novel. Then about sex, rape. I admit I read some smut but it never gave me space to enjoy it in terms of sexuality. Not a priority at all.
I can no longer be specific. Sometimes I don't like the main character who is too stupid, but if the mood development is adjusted to be comfortable to follow, sometimes it removes other unpleasant aspects. Still there are things that must be considered so they can shape the quality of the story itself.
