Now, it's been a while since I watched this series, so my review may be a little superficial, but one thing is certain; This is the only series I actively will try not to ever, ever watch again. And the reason for that is simple: I loved it so very much.
The characters; Everything from backstories, to personalities, relationships, even to their names and how all the names together make up a certain "name aesthetic", made me feel so connected to them. I wanted to cheer for them, I wanted to understand them even more and I wanted to reach out to them.
And then there is the gorgeous artstyle that's soft and light-hearted, yet able to invoke very real and saddened emotions when the situation allowed it.
The story was paced in a way that I never got bored, and I constantly wanted to know how various conflicts were going to be solved.
The impression I have of this anime the first time I watched it is so pleasing and positive that I don't want to ruin it by watching it a second time. I really recommend this series for slice of life and drama-lovers. You won't regret it.
