An older young man who works as a simultaneous interpreter travels back to ancient times, runs a small shop, and develops it into a chain of shops.
What the hell, the original owner of this body liked his half-brother... And committed suicide for him? Life in ancient times was really too busy and there was nothing to do, so life was wasted like this.
Jingjing, my brother has always liked you as a younger sister.
I know, now I don't like you.
Quietly, you have changed.
PS. This is not a brother-sister story - -
This is my first time writing such a long copy - -
