Koi Kaze

Koshiro Saeki works in matchmaking, although his own romantic life has recently fallen apart. A chance encounter with the schoolgirl Nanoka is followed by a disturbing discovery: she is the younger sister he has not seen for years after their parents' divorce.

Nanoka moves in with Koshiro and their father, turning a family reunion into an emotional conflict he struggles to manage. His inappropriate feelings, which began before he knew who she was, lead him to attempt distance and restraint, while the renewed household is unsettled by tensions neither sibling knows how to resolve.
