I was about to drop this drama at episode 4 because of the second female lead (Ming Yue). Since each episode is only around 30 minutes short, I decided to complete it even though the tendency to dropping remained due to other reasons. I don't regret watching it and also don't regret finishing it, but this drama definitely won't make it into my favourites list. It wasn't a waste of time though.

The Story:
The storyline is nothing new or outstanding. It's the typical time travel theme which was okay. I expected that. The villains story is boring and not really worth mentioning. You wouldn't miss much by skipping half of it. You'll soon realise that almost everything in this drama is solved by the uncredited lead character: poison.
It's hard to put much background in a drama with 12 episodes so I think they did okay.
It keeps you interested enough which in my case was mostly because of the romance between the main leads.

Acting/Cast:
I liked the cast, specially the main leads and side characters Xi Feng, Mu Han and Qing Cheng. The acting was good and I think the main leads made a nice couple here.

Music:
I like the title song but that's it. The rest is fitting to the drama but didn't get stuck in my head like some really good OST did. Still I favour music that disappears in the background over unfitting and distracting music anytime.

Rewatch Value:
Close to none. I won't say what the end was like to avoid spoilers for those who want to watch this drama but I didn't like it. In fact I was rendered speechless at the end cause I wasn't sure if I could even consider this an end. It wasn't satisfying for my likings and felt too abrupt. If you want to know feel free to send me a direct message or ask in the comments and I'll answer with a spoiler.

Overall:
5.0 Yes, this looks harsh but I didn't enjoy this much. There was just nothing special about it. Even though I liked a few of the characters I mostly was fighting the urge to skip huge amounts of the episodes. The drama was mostly boring and repeating itself. The end is....well....I wished for something that felt more like an end instead of something like a preview to a second season. Some might find it satisfying, but I didn't like it.
I would recommend this to someone who is looking for a lighthearted, short time-filler in between other dramas. It's okay for a single watch. This drama reminded me of "I'm a Pet at Dali Temple" so if you have watched and liked it, you might also like this drama.

My thanks to Lan Lan for subbing this. Without her, I wouldn't have been able to watch it at all.
