This drama is about 50% sweet romance, which I would rate at about 9/10 and 50% is about working at a publishing house, which is at most a 5/10. I realize that the end result being 8/10 doesn't really compute, but ultimately it comes down to me enjoying the romcom parts a lot & tolerating the business related things.

The romcom part is close enough to realistic cdrama perfection, I guess I would have loved a bit more comedy and faster progress in the OTP's relationship. The production team did a good job maxing out fluff & sugar, no complaints there. It's really nice how the bromance/weak live triangle thing was handled.
The leads are a match made in heaven, I found them a pleasure to watch throughout the entire drama. Also their love story is nicely written and even their short mini breakup felt well executed & timely. I'm extremely happy they did not do that in the final episodes, I hate that!
I did not like the second couple's story very much, there was too much push-pulling. I liked the characters & the actors though..
The cast in this drama is very good overall, right now I cannot recall a single weakly cast supporting character.
Also there was a crazed bitch character trying to take away ML from FL, she appeared nearing the end of the drama. I think that plotline was completely unnecessary, but it was still tolerable, she was rebuffed at 100% efficiency every time.

As for the life at a publishing house, it's easy to criticize many work related happenings, the story is not all that interesting and there are all kinds of villainous, or semi villainous characters. If I look at this having seen many carrier oriented dramas before, then it's still pretty okay. Corporate scheming & infighting are almost always total garbage in other cdramas, here it's not so bad. The biggest issue is that the adversaries had weird & meaningless motivations and they have often done really arbitrary illogical things. The characters themselves are okay, we don't quite reach the cartoon villain territory. The largest annoyance I've had is the biggest crisis plot in the drama, involving ghost writing claims & lots of unreasonableness. I think it would not have been very difficult to come up with a better, more realistic plot involving Asian cancel culture.

I think people criticizing Esther Yu's voice are in the wrong. However around episode 9-11 perhaps there were too many scenes involving childish temper tantrums & fake baby talk :p I don't think it's fair to blame the actress for that though!
