Non-spoiler review:
Visuals: 9, The art style was great and the animation was great as well. The only things I didn't like were a personal flaw in the art style and the abundance of CGI crowds.
Music: 9, The only bad things I have to say is that a few songs were forgettable. The rest was amazing.
Story: 10, My favorite part. Sometimes the characters acted a little weird or out-of-character. But it very realistic, not too cliche, and VERY emotional
Character: 9, I loved the characters that they had. The main characters were convincing introverts and the friends felt realistic as well. My only problem was some forgettable characters.
Enjoyment: 10, Many good emotional moments and relatable characters
Spoiler review:
Story: I loved how they wrote Kotaro and Akane, they really felt like real introverts. How they got silent for a few seconds when something awkward happened or how they actually had friends and weren't anti-social human beings. Those aspects of they're personality also helped a lot to make their relationship feel real, and it really felt like it. It felt like they were made to be with each other, but not in an unrealistic way.
And then we have the ending, wow. It was probably the most emotional ending I have seen ever. At first, it was a sad feeling. We didn't know what was going to happen after Akane's move. And then they show what happens next and the tears continued, but this time because we get to see their relationship evolve until they get married and get a baby. That was easily my favorite part of the story. But there were things I didn't like. Some characters acted weird sometimes (only like one or two times). Like when Chinatsu asks Akane if she can tell Kotaro she likes him. That felt like a pretty scummy thing to ask. Then Kotaro and Akane had like one or two scenes where they acted out-of-character. But other than these flaws, it was amazing.
Art: Wow, the art style was really. The only thing I didn't like about the art style was the white around the characters, which bothered me sometimes when it looked weird. Other than that, the art style was great. But if I want to talk about the animation in the show, you kind of have to talk about the CGI crowds. Sometimes they were just in the background not bothering me, but then there as shots between scenes with the only CGI crowds. It looked really weird when they were in the center of the shots. That was probably the worst thing in the show, the overabundance of CGI crowds.
Music: Again, wow. Yeah, a few songs were pretty forgettable. But the rest, OMG, they were fantastic. Right after finishing the show I listened to many of the songs. They really helped put emotion in the scenes. And when there wasn't any music, that helped too
Characters: Like I said, I loved the main ones. How their introverted side is presented and their personality in general. But what about the other characters. They were all pretty good. Kotaro's friends felt like real friends. And so did Akane's friends, all but Chinatsu. She and Hira were pretty scummy at some points. But they weren't really presented as bad characters either.
Conclusion: So there you have it. It was probably my favorite romance anime of all time. It was realistic, sweet and terribly emotional. Would highly recommend. 8/10
