This is one of the best dramas I've ever seen. I rarely come across a drama that can hold my attention for 16 episodes, much less 40. I loved seeing the main characters grow up, grow apart, and grow back together, and the love story really felt incredibly organic. I'm already looking forward to rewatching it.
The one complaint that I have is I felt the drama weakened after the 30-episode mark. The main couple and the dads got pushed to the side toward the end in favor of wrapping up the side plots. I really feel like this should've been closer to 45 or 50 episodes with how rushed the last 5 episodes felt, to the point that I wonder if they had to make significant cuts pre- or post-production. The finale didn't feel like a finale at all, and some of the resolution felt a little shallow. I would've liked to see Ling Xiao go to freaking therapy for one, and for his mom and sister to actually get some help too.
But overall, amazing drama that had me crying literally every episode, with a stellar cast and so much heart. Definitely a highlight of 2020 and a go-to comfort drama now.
