I'm a bit in between on this one. Sometimes the "character development" is a bit over the top. I mean, like, one of the major defining characteristics of the heroine is, she's shy. And OK, I get it that inevitably part of the project of the shy girl coming of age thing is "overcome shyness". Fine, it's bad to be so shy you can't function. But she ends up being in the school Miss Congeniality or whatever contest, and then deciding, apparently mostly as a challenge to herself, to pick teaching as a career. WTF?! No. You challenge yourself by doing things that are a bit out of your cloistered comfort zone, you do not take on careers that will last for decades where you have to stand up in front of people and talk all the time every day. In real life this would probably make a person like her miserable, and the feeling that she has to go that far is part of this "SHY == BAD", "INTROVERTS MUST CHANGE" thing I see quite a bit and find quite annoying.
Also there's this recent arc that's all about a side character being a model and I don't give a damn about models. I usually skip manga about models, idols and so on, and suddenly this turned into one for a while; bugged me.
However, at the same time there's a lot of good stuff. And the thing is that even when it's doing bad stuff, it's doing it pretty well; the art is good and expressive, and the major characters feel like nice people somehow (even the side ones who often aren't actually acting nice somehow feel sympathetic). So, overall so far I'm basically glad I stuck to it. But it can be frustrating.
