The Garnet that Sparkles in the Junk

Synopsis

Kanae, an assassin with no attachment to life, encounters Sara, a male half-vampire, at a garbage dump. When Sara attacks him, Kanae remains indifferent, even as Sara bites into him or intrudes into his home. Abandoned by his parents as a failed vampire and desperate for blood, Sara proposes a deal: in exchange for being his source of blood, he can help manage Kanae's rough life. Thus, they begin a physical relationship, driven by the arousing effects of bloodsucking. As their body heat intertwines, the warmth between them begins to dissolve their shared loneliness.
