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.
