A person wakes up inside a story during childhood and realizes they must stay close to a feared villainess in order to survive and prevent their condition from getting worse. The problem is that the villainess is cold, sharp-tongued, and pushes everyone away.

Even so, they continue staying by her side and slowly grow close while trying to change the tragic events of the original story. Eventually, however, they are forced to separate.

Ten years later, the villainess—still secretly caring about them—sends a handsome bodyguard to protect them. But the more time they spend together, the more familiar he feels. His actions, words, and habits strangely resemble the villainess from the past.

As their relationship becomes more romantic and confusing, a shocking truth begins to surface: the bodyguard may actually be connected to the villainess in an unexpected way, and the “villain” of the story may not be who they originally thought.
