A Vampire’s Life of Living Off Others

Transmigrated into the body of an exiled vampire noble, I somehow get lured into the harem by a sharp-tongued empress as her male concubine? Others risk their lives when they drink blood. I can read minds! Three times a day, I can copy a beauty’s skills: the yandere holy knight’s swordsmanship, the elf priestess’s healing magic, even the empress’s political scheming... They all become my ticket to living off others! But why does that tyrant, who makes me warm her bed by day and chains me up with silver at night, keep dissecting vampire corpses in a secret chamber? Help! Is this cushy life a sweet trap set by the empress, or my trump card for turning the tables? When a thousand-year-old vampire’s cunning meets a deadly mastermind, will this throne be a life of luxury or a fatal cage?
