I rarely enjoy Chinese Drama since it's usually draggy and too melodramatic with not so good humour. This one is an exception! The story is not entirely in line with the original novel it is based on, but I think it's better written with some artistic licence taken by the scriptwriters for adaptation into the series.
It would be weird to watch if the girl is 14 years old marrying a much older man (which is typical of a girl's age of marriage in Chinese history) according to the original story but that eliminates the Chinese title's relevance (General's little wife). The storyline and characters are well written with good acting, a very rom-com story-line and, as usual, a slightly annoying female lead. I love the OST and background music. Also, an exception to most Chinese historical drama is that there are lots of very realistic romantic flirting, kissing and intimate scenes between the couple as new husband and wife early on.
Tang Ming and Ceasar Wu have fantastic chemistry between them. Both main leads did a good job acting and bringing out their characters. Ceasar Wu had improved his acting skills much since Chang An Youth. Overall, it's well done and not overacted like a lot of Chinese rom-com. It's a plus that they're both eye candy. The main lead female character is very witty and bratty, sometimes annoying. Still, it is justified by her spoiled upper-class upbringing with a mix of harmless delinquency due to being bullied by her sisters. Caesar Wu's portrayal of the General is very realistic and cool, but I'm afraid I disagree with the story description that the General is icy. He's not icy at all but a quiet, deliberate, caring and lonely hard-working man. His sense of humour is there but muted until he met his match. The romance between the two main leads is funny but not realistic (but this is a rom-com). The humour is well written, and I laughed out loud so hard it made my family wonder what I was doing? The fight scenes are well-coordinated, though there are few of them. The clothing is, as usual for the Chinese period drama, elegant. This series is definitely a must-watch as a period rom-com if you enjoy Chinese Drama of this type. It is also a good watch if you don't like the draggy Chinese Drama; this one doesn't feel draggy. The dialogues are well written and funny, so pay attention to it. The main characters' lines are often witty. For someone who often loses patience with Chinese drama, I really enjoyed this one and finished it.
