Born into a distinguished family, the young lady “Claire” grew up without any setbacks or hardships, and with a beloved fiancé, her life was truly smooth sailing.

But one day, when she broke a tarnished jewel that had been mixed in with the gifts, a succubus sealed within the jewel appeared and cursed her.

The curse caused her to become sexually aroused by the first person she saw, and although panicked, Claire was overconfident that she only needed to see her fiancé.

However, a servant who had entered the wrong room appeared, and the curse was activated when he accidentally caught sight of the man. Of all people, that man was an incompetent servant who the young lady usually treated like a lackey.
