College student Kaoru Hanabishi has cut ties with his wealthy, unaffectionate family, so he assumes the worst when Aoi Sakuraba, his betrothed from a childhood arrangement he'd nearly forgotten, turns up in Tokyo after eighteen years apart. Aoi, heir to the Sakuraba fortune, has come to find him on her own terms, not to drag him home, and the two begin rebuilding a bond neither expected to matter again. The manga's original serialization ran in the seinen magazine Young Animal.
