There were parts of this that I really enjoyed. Then there were other parts that were so inane. It was a mixed up mess in places, particularly at the end.

Good: FL did not seem to fit the character, but grew on my. 2nd FL and both ML were really good as well as the other two couples.
Little brother was perfectly annoying as he should have been.
Sets were good and disaster sequence was also well done.
Chen was a great character and the actor was really on point with the reactions and emotions.
The little girl and her guardians were a delight. Auntie bickering in that voice. She is one of my favorite character actors.
Xiaojia character and sequences were very well done. Took me a couple of episodes to figure him out.

Bad: ongoing hallucination device became overdone and just irritating.
The music became irritating in the last half. It wasn't bad music, but using theme songs as plot devices is poor directing.
On and off and on and off. Romances were too melodramatic too often. The third couple were more straightforward until late and that was a new irritation the director/writer did not need.
The ending was an unfair, convoluted, without reason mess.

My main complaint is the story used mental health and the difficulties dealing with and the PTSD, though not named, was treated fairly well. It is a journey to overcome PTSD. One journey I've taken myself. Then in the last two episodes a sudden event? It cheapened the whole story line. And for no reason. I realize this is a book adaptation, but disappointing isnt a strong enough word. And the final scene, is it real or is it not? That was unfair to audiences. The last two episodes were just tacky and we got to see the bratty brother in trouble but not the baby?
