S-Class

On his 21st birthday, Jisung reports dutifully for the annual blood screening. A formality, really. Like most commoners, he expects to be ranked D-class: unremarkable, unmatchable, and free to live his life far from the reach of the vampiric elite.

But when his results come back, everything changes. Summoned to the palace and bound by law into a formal donor match with the Crown Prince himself, Jisung is thrust into a world of velvet, fangs, and ceremony. What should be a distant, transactional arrangement quickly spirals into something tangled and consuming, and the more he gives, the more Minho seems unwilling to let go. As desire, power, and ritual blur, Jisung is forced to confront the truth beneath it all: how much of what he's feeling is real... And how much of it is just the bite.
