To be honest, I rarely watch a Cdrama to the end. And even though I rate this drama poorly, all things considered, I did finish it. So that's something. As other reviewers have said here, there really was no story at all - just good-natured people dating and supportive friends. Here's what I enjoyed:
1. The information about voice dubbing culture and fandom in China (something I've always been curious about).
2. THE FOOD as love-language.
3. The "friends/colleagues having fun vacationing together" vibe.
4. The travelogue to Guijin (bucket list location)
5. No backstabbing or miscommunication tropes

Here's what troubled me:
1. The lack of nuanced characters or character arks (nobody is that good all the time).
2. The age-gap thing, how ML pursues FL. All they have is surfacey love for each other based on their voices? And he's way too mature for her. She acts like she's 12 - is that a cultural thing? Do college aged women act like that - all obedient and eager to please? I would definitely find him sus, if he weren't so sweet....
3. The whole thing seems like a Chinese propaganda show.
4. NOBODY SLEEPS WELL.

Here's what I'm curious about:
1. Why isn't sleep prioritized?
2. Is their representation of the voice-dubbing and traditional Chinese music culture accurate?
3. Wouldn't her parents have been more involved?
4. How are there so many cousins, while China had the one-child policy in place? I really don't think that Cdramas have a realistic portrayal of the effect this policy would have had.

Overall, I think I continued with the show until the end because I am really heartily sick of what's happening around me - awful politics, environmental disasters, etc, - that I just needed a break. This show was a break. The people are good and well-intentioned, they all think of others before themselves, and care about relationships.
