When Edita Lutensbach finally wakes up after an accident, her loved ones let out a sigh of relief. But unfortunately, the person who has woken up inside Edita is someone from a different dimension. Feigning amnesia, Edita learns that her doting father is an emperor. However, she is his illegitimate child, which puts her in a precarious position. She also discovers that her fiancé has died and that the noble Duke Brant Albrenovich has promised to take on that role. Edita wants to get along with her mysterious new fiancé, but his abrupt changes in behavior are enough to give her whiplash. The two seem to share a complicated history that, unfortunately, Edita can’t recall.
