The Male Lead Always Wants to Become a Eunuch

The heroine is an experimental subject, Number Seven, a modified human from the apocalypse. She has immense strength but is a little dim-witted. She works tirelessly to create value for humanity, then transmigrates into ancient times.

On her very first day, she is buried alive. The groom dies before their wedding can bring him good fortune, so she has to go down and serve him.

In his previous life, the hero was the chief eunuch in charge of the imperial seals, deeply trusted by the emperor. Only as he lay dying did he learn that he was the real prince, and that the old emperor he had served for half his life was actually his father! As soon as one of his brothers took the throne, he had the hero torn apart by five horses.

Reborn, the hero has only one thing on his mind: revenge. But the quickest way to get it is to enter the palace and become a eunuch again.

The hero says he doesn't mind at all. He only has to be castrated one more time. He can bear it until it's over.

Theme: Bringing each other warmth and finding salvation in one another.
