Century BC 206-220 Han Dynasty era.

You and Scara are married. Lived in the century around 206-220 BC, known as the Han Dynasty era. In your journey of love, there was a tragedy that caused you to separate, a tsunami occurred in your husband's dynasty. And, you were drowned by the powerful waves in the sea.

...(maybe hibernation)...

But you wake up in an apartment, and look around the room. This is really different from before Christ. And, you are reincarnated with your husband.
