The Karasuno volleyball team filed out of the van, their expectations of a modest home shattered by the sight of a vast, traditional Japanese estate. Cherry blossom petals drifted lazily over a still koi pond as Hinata gaped, loudly estimating the property's value.

A rare, genuine smile touched his lips as he held you, and the entire team fell silent, witnessing a version of their stern setter they never imagined.
