I decided to watch it as I've heard some good reviews about the first few episodes, and it definitely blows my expectation. I can't really tell that this was a lower budget production at first as it got great cinematography and overall good story & acting.

Pros
- Zhaomo
They are hands down my favorite couple in dramaland now. They are the standard and I just love their relationship so much. The romance development is amazing, the pace is just right and I really could believe in every stages of their relationship. I really love their married life as well, it's so much more intimate than what is shown in other dramas imo.

- Great cinematography
Director is the biggest asset in this drama, he have clear direction and is a good storyteller. While I love the main characters, I also love to see side characters have their own memorable shot, so I really like this director's style. I am definitely looking forward to see his future works.

- Solid script
Script is solid overall. Characters are well written and have their own highlight, story have a clear direction, plenty of good dialogues throughout, and I like the resolution as well. There are some plot holes here and there, but it's quite minimal and still within acceptable level to me.

- Good acting
The acting here is overall pretty good and nothing bothers me, everyone fits their role quite well.

- Good ending
Honestly I was so worried it's gonna end so badly since I don't like the major plot development after their marriage (especially for episode 27-32), but I'm glad it ends on good note and overall still makes sense to me. Some of the storyline could be better though (Songhan x Ansu, Jiyong, Empress x Emperor)... but it's a pretty good ending considering other dramas that I have watched in recent years, so I'm very satisfied overall.

Cons
- Uneven quality for both directing and script
The directing -- some episodes in latter half was not as good as the beginning, the dip in quality is more noticeable since the beginning was really good imo. Thankfully it got redeemed on the last few episodes.

The script also suffer from this as some characters or arc are not that well written, in particular Songhan x Ansu, Jiyong, and Empress x Emperor storyline could be better. I'm not sure if it's because they run out of budget or the censorship cuts few episodes, but I really wish Blossom have few more episodes to develop the latter half better as the plot was too jam packed towards the end.

- Action scenes feel lacking in last episode
Action scenes in the beginning was really good and it's what caught my attention the most... but unfortunately the last battle leaves more to be desired. Again I'm not sure if it's because of budget or time constraint, but I wish the last battle is grander.

Overall I'm very satisfied with the series. I wouldn't recommend it if you're looking for something perfect because it's not... but if you're looking for something fun with amazing leads, good cinematography, compelling characters, and good ending, then please try to watch it.
Please note that my rating is slightly higher as I really enjoyed watching it and the ending makes me feels like it's worth the express fee that I paid.
