Ningyo no Ie — The Mermaid's House

Summer of senior year. Asahi, unsure of her future, returns to her seaside hometown for the first time in seven years. Waiting for her are her best friend Chihiro and another childhood friend, Mio. She remembers Chihiro — but somehow, not Mio.

She spends the last three days of summer at Mio's house. Late one night, Mio leans over the sleeping Asahi and kisses her. Chihiro, asleep right beside them, sees it and is shaken — she had just told Asahi that the one she loves is Mio.

Chihiro loves Mio. Mio kisses Asahi. And Asahi, all along, has loved Chihiro. A mermaid-legend mystery and a love story between girls.
