Yaoi / Lezhin's comic.
Vampire x human.
Unusual vampire whose pleasure is to be dominated by humans. Apart from the BDSM which was good, there's more than sex in the plot. A forgotten past, a forbidden romance, treason, action, there's just all in this story which makes it one of the best addicting manhwa.
