I'm quite surprised the main reviews I saw for this are rather negative. Although I know enjoyment is subjective! Still, I feel personally that it deserves a good amount of praise.
I'll start off with a few things I didn't like, which is primarily Yi Zi Tong. A lot of things pertaining to him felt unnecessary and were just generally extremely frustrating. Could have done without 85% of his screen-time. No offense to the actor of course, as he did a great job playing the character. Most other issues I have with the show are a by-product of his presence.

Shi Lei and Jin Yu Zhen definitely do have a slow burn romance, and there are some typical tropes used to progress their relationship, but I never minded. There were a lot of ups and downs between the two, where they got closer and then a bit distant again, but I found the ending to their story to be satisfying and lovely. The two had chemistry that was palpable at times, and any of their sweet or tender moments together were incredibly well done.

Shi Lei's mom is one of my favorite aspects of the show. She's sweet and caring, and you can tell she loves and supports her son in a genuine way. I could recite the entire scene of their conversation and him coming out, as I was that moved by it, but I won't do that. Just know that I could and would.

At first, the relationship between Gang and Si Qi was rather bland to me, but they grew on me and I really appreciated their story. They were kind and straightforward with each other. There were times that misunderstandings could have driven a wedge between them, but they instead just talked with each other. No running away, no forced drama. Their relationship ended up being a wonderful part of the show for me, though I know some others might not care about them so much. For me, they have a very realistic - feeling relationship.

I tried to keep things rather vague to avoid just spoiling the whole show, so I don't know if I truly sold my point very well, but the gist is that it's very charming.
Once again, my biggest complaint was Yi Zi Tong and oh boy could I write an entire dissertation about my issues with him and his presence, but I'll spare you.
Still, I've watched this 2+ times already and will do so again as it's just a guaranteed sweet watch.
I'll only briefly mention the music, since it has been awhile since actually watching the show; I can't recall the OST in full, but I remember liking a lot of it.

Overall, I'm aware this isn't a perfect show, and it might not be for everyone, but I highly recommend watching it for yourself since the viewing experience can't fully be delineated through words.
