Xiaoxia starts a new life on Earth after retiring from her old one, falls in love with a human named Ryan, and marries him.

Ryan is a soldier who fights against incursions by extraterrestrial life. Xiaoxia hides her identity and helps out from the rear as an advisor, but...

As time goes by, Xiaoxia suddenly realizes that something seems off about Ryan.
