This is not a book that requires a lot of mental engagement. It's mostly tooth-rotting fluff. There's a couple issues with the initial establishment of the main CPs relationship, mainly because He Cheng Ming comes on REALLY strong and is not interested in no, but he is, for the most part, respectful of Ji Liao's boundaries. Their relationship very quickly comes together and most of the rest of the story is He Cheng Ming being a doting, loyal boyfriend. All of the conflicts in the story are resolved incredibly easily, although YMMV on whether or not you're satisfied with that conflict's resolution.
The second CP is trash though. I didn't even bother to read the extras because what little you saw of it in the main text told me I was NOT going to be happy with it.
Another plus is that, for the most part, this story is really good to its female characters, which shouldn't be something I have to say but there you have it. YMMV as well on whether or not you find fujoshi characters overtly shipping people who they actually know discomfiting (I really do) but Xu Xiao Ming is a steadfast ally to Ji Liao and even Meng Yao Yao, who had a crush on He Cheng Meng, takes being shot down with grace and does what she can to support their relationship. I have mixed feelings on Jiang Qi because I really, really wanted to like her and if you can ignore her blatant willingness to try and obtain someone who already has a significant other, she is an awesome big sister-type character. But also. She was absolutely willing to wreck her brother-in-law's relationship just because she thought his boyfriend was cute.
Overall, the story is a simple read and a nice way to pass the time but it doesn't particularly stand out in any way.
