She is the head of the Mitnadel family. His status is supreme and unrivaled.
He is second only to her in status and ranks first among the elders of the Mitnadel family. One person is inferior to ten thousand people.
She and he were a couple that everyone admired, but one day, when she knew what he was thinking, she resolutely abandoned her noble status and fell into human reincarnation, just to fulfill him.
Until──he was in danger.
She thought she would let go of her feelings after reincarnation many times, and she also cast a spell before reincarnation to make herself forget what happened here when she became a human. However, after recovering her memory, she still could not forget it.
For him, she decided to return to her family for revenge.
Eliminate enemies and remove obstacles just to allow him to have a future with her.
Although, that would destroy herself; even though, it doesn't matter if she turns into a murderer.
Isn't it?
Everything is just for love and promise.

((((The description, cover, and title of this book may only be tentative, sorry for this)))
Hehehe, the introduction is so well written that Xiang Nanzhu is weak... (Lower head and admit his mistake)
Actually it's not Europe... (Emphasis added)
The male protagonist is also very powerful and says that it's just the female protagonist who is showing that he is secretly hiding it.
