Okay. The 7.5 is mostly because of the chemistry between Mu Ren and Li Chen. If those two hadn't been included I doubt i would have finished the series. I didnt care for Li Chen pushiness at times. I have no complaints really about Mu Ren. Ultimately, i found their realtionship to be cute for the most part and the chemistry was great.
However, the Xing Si and Yong Jie storyline was hard to watch. Yong Jie raped Xing Si. Period. I found it disturbing seeing them together afterwards and it was like Xing Si felt like the guilty one. The handling of sexual assaults in the series was horrific.

Finally, the women shipping them in the office was pretty cringey. Its quite common in the genre, but its still very cringey to me.

Overall, I would possibly watch again, but to be honest I'd only watch the Mu Ren and Li Chen story.
