Tonagura!

Kazuki has spent the last ten years waiting for the day her neighbors return to their old home. Back when they were children, Yuuji was always around—playing with Kazuki, her older sister Hatsune, and Yuuji’s sister Marie—and Kazuki quietly nursed a first love she never managed to confess before his family moved away.

When Yuuji finally comes back, the reunion doesn’t match the sweet image she’s held onto: he’s bolder, far more suggestive, and quick to throw her off balance. With both sets of parents away in South America, the two households end up closely tied again, and the awkwardness only escalates once they’re sharing the same school—forcing old feelings, new misunderstandings, and everyday chaos to collide.
