A girl wakes up inside the body of a doomed noblewoman from her favorite story—someone who was supposed to die early from a deadly illness. Accepting that she may not survive, she decides to enjoy her new life by fully embracing her role as a devoted fan of her favorite character and his world.

Unexpectedly, she survives by awakening a power that wasn’t part of the original story, changing her fate completely. Even more surprising, she ends up bonding closely with her intimidating in-laws and an overly affectionate husband, who constantly flirts with her and showers her with attention.

As she tries to enjoy her peaceful “fan life,” she slowly realizes that the real danger around her may not be her at all—but the person closest to her.
