This series is one of the best romance manga I have read yet, and probably it would retain the spot for a long time. However romance is not really the main point of the story, just an integral part of it. It is more about growth, in the form of accepting what you want to do in life, and working towards it. Atleast I get that impression. The bonding between the 2 main characters is pretty great, we can feel them getting closer throughout the series.
The art is also cool, and enhances the chill soothing vibe of the manga. Mangas like these are better read slow, as they don't contain any earth shattering twists and turns and give more time to make you immerse in the setting and characters. There are a lot of moments in the manga where I like to go back again, as the moments are that iconic despite everything being so slow paced and chill due to the art and the writing. I have to commend the translators too as they did an epic job.
The last volume where there is a parallel universe going on where the MC and Kondo are in a high school at the same age is pretty great. The conclusion was nice too. It completed the character arc of Akira and you feel happy for her growth.
If there is anything I'd like to complain about, it's that I wish Kondo had gotten some more respect or success throughout the series. He is mostly just lamenting about how he has gotten old and doesn't deserve all the niceties that come with youth.
Akira gets success again when she restarts her running career, but Kondo doesn't get any win. I guess you could say that's not the point of the series, but I feel like my boi was done wrong(a bit).
Also the side characters were pretty forgettable except Akira's work buddy. It's not that they were bad, just that you don't necessarily wish to see them again and again.
As per the title, rain is given a new meaning in the manga, I won't be able to properly express it in words, but it's [color=Red]beautiful[/color], just like the series.
