I read this on Lezhin Comics and loved it. The earth was plunged into a second ice age following a global disaster, and vampires have evolved to become the dominant species, raising humans as livestock. A human called 'One' becomes acquainted with Shell Overlord, son of the owner of the blood bank where One is employed - a rarity among humans. Shell realizes that his vampire pheromones have no effect on One and comes out to him as an "abnormal" - a vampire who wishes to be dominated by humans. One, who despises vampires, finds himself in what amounts to an S&M relationship with Shell, who is actually a tender, kind person, and One's worldview is rocked when he falls in love with him and discovers new information about his own father. But beyond their love story is a plot to destroy a hopeless, hellish existence for humans by eliminating all vampires.
Wonderful world-building and absolutely gorgeous art. There are a lot of chapters which are purely pornish, but there's a lot of emotion and some interesting plot stuff too. This author obviously thought out the world and plotted the story before she began creating. I read the story start to finish in about twelve hours. If you can afford the credits, please consider buying it on Lezhin to support the author.
