I'm shocked this has no reviews!
It's been a while since I've read a story that was profound without being melodramatic, and compassionate without being wholly unrealistic. It's not a yuri or BL manga, so there's a healthy helping of homophobia in some chapters, but it never feels like sad gay schmaltz. Yoshida depicts what feel like lived experiences, even when stretching outward beyond the "average" human experience -- domestic abuse, suicidal ideation, internal homophobia, etc.
Her style of portraying characters always has an element of realness to it, rarely outlandish or overly gag manga-like. Scenes with silly faces feel like cartoon interpretations of real life events. It doesn't feel set up for the joke... or for the drama, for that matter.
The story itself flows particularly well, sometimes chronologically, sometimes not, always providing the right amount of information at the right time. Stories jumping between multiple perspectives can get confusing, muddled, or just overly ambitious, but Yoshida reins in the complexities of her characters' relationships with her expert pacing (and a joke here and there about how silly the love polygon ends up being).
If you can handle the various triggers (child abuse, familial abuse, mild homophobia, Teens Being Really Fuckin Mean To Each Other, etc) then I highly recommend this. It's one that demands a reread as soon as you close the second volume, now having the context that you craved right from the start.
