Blue Box is a high-school romance by Kouji Miura that runs in Weekly Shonen Jump. The setup is small and specific: Taiki is a first-year on the badminton team who has a quiet crush on Chinatsu, an older girl on the girls' basketball team he sees every morning at practice. Then she ends up living under the same roof as him. That's basically the whole engine, sports plus early-morning practice plus a crush you really want to see work out. If you like sincere, slow-burn romance with a sports-club backdrop, this is right up your alley.
The art is clean and expressive, and Miura is great at the small stuff. A glance held a beat too long, the nervous gap between two people who haven't said the thing yet, the way a gym looks at 6 a.m. with one other person in it: those quiet moments are where the book lives, and they land.
It also treats its characters with real warmth. Nobody here is a villain, and the drama comes from ordinary teenage feelings handled with care rather than from contrived blowups. You end up liking almost everyone, which makes you want to see all of them do well, and that goodwill carries a lot of scenes that would feel flat in a colder story.
The sports and the romance feed each other, too. Practice isn't just background. The discipline, the early mornings, and the shared ambition are part of why these kids respect and like each other, so the badminton and basketball matter even if you don't care about either sport. It gives the romance something solid to grow out of instead of leaving it floating in a vacuum.
It's slow, on purpose, and that won't suit everyone. If you want big dramatic turns or fast progress, Blue Box asks for a lot of patience, and some chapters are content to simply hang out with the characters.
The conflict also stays gentle. There's a love-triangle shape to the story, but the book is too kind-hearted to wring much tension out of it, so a few stretches can feel like pleasant treading water. And the supporting cast and tournament subplots, likable as they are, sometimes pull focus from the central relationship just when you want the story to push forward.
Blue Box is a warm, good-looking romance that cares more about feelings than fireworks. If that sounds appealing, it's an easy series to fall for, with sharp art and a cast you'll actually root for. If you need plot momentum or high drama, it may test your patience. Read it for the mood and the characters, give it room to breathe, and it'll win you over.

Not yet. It's still running in Weekly Shonen Jump, though the author has said it's heading toward its ending. Collected volumes are out in English from VIZ Media.
Both, but romance leads. The badminton and basketball are a big part of the setting, while the heart of the story is the relationships.
Yes, Blue Box has a TV anime adaptation, so you can try that if you'd rather watch than read first.
