Yatarou has stayed close with two childhood friends his whole life. Hinata is shy and quietly feminine; she's been living in Tokyo and has just come back. Honoka is tough, tomboyish, and has always been there for him. When the three reunite after years apart, something shifts—Hinata and Honoka both begin fighting for Yatarou's attention in ways that grow increasingly intense and strange. He has to make a choice. Whatever he decides, it will leave a mark on all three of them.
