This is such a sweet and wonderful mini-show. The storyline is quite simple. A modern girl has an accident on a film set. She wakes up as a concubine in historical times. The emperor becomes her task towards getting back to the real world. She solves some more or less easy tasks but her mission is to become the empress. That mission gets complicated when other characters get in her way and she starts to fall in love with the emperor.
Acting wise this is actually high quality since the main actors are rather skilled. Nice to see that in one of these mini-shows.
So, if you like a romantic and interesting mini-show, this is well worth watching.
