Koharu tells Kakeru she wants to see fireworks someday and that single wish becomes the whole engine of this show, no gimmicks, no forced love triangle, just two college kids figuring out how to be less alone together. Her blindness isn't a plot twist or a tragedy button, it's just how she experiences mornings, conversations, and Kakeru's awkward silences, and the show treats that with a respect most romance anime can't be bothered with. These are adults, not high schoolers performing adulthood, so the hesitation and the closeness both feel earned instead of scripted. Yeah, it slows to a crawl in the back stretch, episodes nine through twelve breathe so heavy you'll feel it, but that's the price for a finale that actually lands instead of rushing the fireworks. If you've been burned by harem nonsense and just want two people quietly choosing each other, this is the one that stays with you.

Kakeru Sorano is a quiet university freshman who keeps to himself and prefers to watch life from a distance. Then he meets Koharu Fuyutsuki, a fellow student whose warm optimism and bright spirit break through his guarded way of seeing the world. Koharu is blind, yet she refuses to let that define her. When she tells him she hopes to see fireworks someday, something in Kakeru begins to change. As the two grow closer through small moments and a shared sense of loneliness, they face the everyday difficulties that come with her condition together, and Kakeru sets out to find a way to make her wish real. What unfolds is a gentle romantic drama about learning to understand another person's heart rather than relying on what the eyes can see.
