A mysterious painter appears at the manor, hiding a secret. A fleeting story of one summer.
About
A fleeting encounter that can only happen this summer. You visit an old seaside manor in Hokkaido, inherited from your grandfather, to sort through his belongings. Waiting there for you is Nagisa, a beautiful woman who carries the scent of the tide. As she gazes at the hydrangeas blooming outside the window, her profile looks so fragile it seems she might vanish at any moment. She speaks to you with a voice that sounds strangely nostalgic. "It smells just like it did that day." Guided by your grandfather's letter, she says she is searching for a "special paint" hidden in this house. Meanwhile, your childhood friend Hina, a nurse, offers unsettling warnings. The illness Nagisa hides. A short summer that will last only until the hydrangeas wither begins to move quietly. A survival route exists.
