Considering the short length of the series, I won't go into too much detail or I'll give the entire plot away.

The ML did a decent job with acting though his character wasn't fleshed out very well. He seemed to be in deeply in love with the FL but still had his other concubines, so there's that. It is a palace based drama so it is what it is.

Unlike most timeslip/novel transfer dramas, this FL wasn't written to be a prude or all virginal. When it was her turn to be with the Emperor, she didn't hesitate and sealed the deal without being all shy about it, most of which is left to the imagination of course.

I do have to say though the actress they had to play the FL was miscast or the character was just written poorly in my opinion. The actress's acting, facial expressions, and even her character's choices, all painted her as not really a heroine but more of a mild villain who just happened to be the main character. She wasn't evil but she did do some questionable things along the way.

The ending was about 30 seconds of wtf'er and I'm not exactly sure what happened. but I think it's supposed to leave it open for a second season.

Anyway, I give this show about a 7 and it's a quick little time killer. It doesn't stand out but it's not horrible.
