To save Alexis (her “ultimate favorite” from a past life) from falling into darkness, she decides to enter a contract marriage with the young Alexis, a boy who has lost his family. During their married life, she gives Alexis all her affection, as he has suffered abuse from his family for being an illegitimate child. Then, three years later, just as the contract stipulates—“We’ll divorce when Alexis comes of age”—she leaves his side, carrying a secret. A wife who vanishes without a trace, hiding a secret, and a husband who ends up losing the memories of the woman he loves. Two people who must have chosen different paths, yet reunite unexpectedly eight years later. And to top it off, Alexis has become an emperor known for being cold and ruthless…?!

A sweet, thrilling, and mature love story in which, even though they keep thinking of each other, they continue to miss each other at every turn.
