While the plot summary sounds kind of same-same to a number of period romance/rom-com where a cool, handsome ML meets and falls in love with a cute, feisty FL, the actual story telling and pacing placed this show well above most of the pack.
You might groan a little as the show opened with the FL cross dressed as a guy and running amok in the city's marketplace but it soon took a different track as more of her background was revealed. The fact that she actually accepted the arrange marriage and decided to turn it to her advantage was refreshing and very engaging. There were quite a few laughs in the first few episodes when she lorded over her shell shocked new husband even though he was a famous general with a killer reputation.
Another welcomed change was when they put in the typical divorce/breakup trope very early in the show and gave it a nice positive spin resulted in more laughs and character growth. This is a major contrast to when most c-drama would settle into a few episodes of despair and silent longing.
The OTP had fantastic chemistry. The FL was a strong character who stood up to bullies, will not accept defeat and willing to fight for her goals. Just as well that the ML is cool (not heartless) but smart and knew that she was his soulmate and gave in to her completely. Once the push-pull and doubts were settled, their love was true and deep, their trust unwavering and unquestionable.
Overall, the support cast were solid. Some of the younger actors were a little weak but they are not carrying a lot of weight so it was ok. Some of the cuteness came from the secondary pairings once the OTP settled into their married life. Even then there was still a decent amount of skinship and feels. Just a little less flirting.
The OST was surprisingly good. The main theme was well matched to the show and was used extensively.
Now for the not so good bits. The second (or was it third) sister was very annoying and a real trouble maker. That is typical for this type of drama but once again, she went unpunished even though her big mouth got the whole family into serious trouble. All was forgiven by the end of the show and everyone moved on as if nothing had happened. Weird to say the least.
Speaking of ending, the last episode was mostly rainbows and unicorns and tied up all the loose ends. That is all well and good as fan service goes but the plot leading up to it was surprisingly weak and contrived. Contrasted this to the writing for the whole show which was solid, well paced and consistent. It was a little disappointing.
Overall, enjoyed it very much, highly recommended.
