In a Summertime Saga–inspired storyline, the tale follows a new transfer student who arrives in a quiet town carrying a difficult secret a rare terminal illness their mother hopes they can forget about, even briefly, by starting over somewhere peaceful. As the MC settles into their new neighborhood, they meet a customizable next-door neighbor who becomes the main romance option, echoing the branching routes the Summertime Saga series is known for. Despite trying to stay distant, the MC slowly forms a gentle bond with them through small moments, honest talks, and everyday warmth. The demo reaches its emotional peak when the neighbor discovers the MC standing alone in a glowing field of butterflies, a scene that blends vulnerability with hope and sets the stage for a future storyline filled with heartfelt choices, quiet drama, and the kind of character-driven progression that defines Summertime Saga.
