I enjoyed this the first time I read it, but the story felt a bit disjointed. Turns out, the site I originally viewed this on had messily uploaded both the "Joker" and "Online" versions together. After going back and re-reading the two sides of this series in order here on Dynasty, everything makes a hell of a lot more sense to me.
The only weird thing is that this version starts out (at least to me) much sillier than the "Joker" version, but ends up becoming the much more heartfelt and grounded of the two. I liked the "School Dance" ending, but I prefer the more grounded and heartfelt ending of this version. Ultimately, I'd recommend alternating between the two as you go, as the story will make more sense, as the two versions sometimes reference events from the other.
And finally, I'd just love to say that I'm in total agreement with other reviewers about Grandpa Azuma! He's such an effortlessly cool character- he's suave, confident, and completely devoted to his family. He also seems to have strong genetics, as both Aoi and Manabu (in their own ways) bare a stunning resemblance to him
