wurhvaer[sound of discomfort], I've been exposed to Christine Feehan Carpathian book serie.
The hope of every Carpathian male is to find his lifemate, the woman he will ritually bind to him for the rest of their Carpathian lives. In the absence of their lifemates, male Carpathians by the age of 200 cannot feel emotions, see colors, or dream.
I try digging around to find some redeeming stuff about it, but nope, it's only got worse... In addition to depression , the older they get without a partner, the more likely they are going to turn into violent incels vampires or to commit suicide to protect their dignity...
