A romance ADV set in summer. An everyday summer spent with my little sister and childhood friend. But 'that summer' and 'this summer' are special summers — Set against two summers, past and present, this adventure game depicts the wavering feelings of a shy, gentle little sister, and a childhood friend who feels like a buddy but is actually bashful. With the sea, festivals, and homework... a heart-pounding journey awaits through summer events. [Translated from the dlsite]
