I recommend Backlight
Distorted Soul (gorgeous art), Toxin, regas, steel under silk, how to survive as a player, blossoms of the white night, bongchon bride (personal fav though MC is the only pretty one), two empires the slave of the empire are all great manga that are dark, psychological with beautiful MCs and MLs
Also Doku wo Kurawaba Sara Made!
These both look interesting thanks!
Stigmata and Turning!
I highly recommend you, wolf in the house, especially the 2nd couple ! All the side story is about them
First part of the story with main couple is more light
Yes Wolf in the House is so good!
Can anyone recommend me more yaoi like this please - dark and phycological and with gorgeous MC and ML? (Those two are genuine so hot together)
Under the green light, flashlight, king's maker and shutline are my other favourites for reference.
