Cherry is een jongen die niet goed kan communiceren en uit zijn gevoelens met het schrijven van haiku's. Hij draagt altijd een koptelefoon, zodat hij niet hoeft te reageren op andere mensen. Smile is een meisje dat altijd een mondkapje draagt om haar grote voortanden te verbergen. Ze maakt video's over schattige dingen, maar ziet zichzelf niet zo. Op een zonnige dag ontmoeten ze elkaar in een winkelcentrum. Ze worden hechter en brengen samen een magische zomer door.
Ja! de film サイダーのように言葉が湧き上がる is nu beschikbaar om te kijken op Netflix in Nederland.
