Koizora LaLaLa: Sora ga Boku ni Warau kara

Sora experiences a difficult day after receiving a poor test result. In a moment of sadness, she crumples the paper and folds it into an airplane, which unintentionally takes flight. Ruka, a classmate, happens to catch the flying paper. This chance encounter marks the beginning of a gentle, heartwarming relationship between the two. The story also incorporates two additional one-shots: one involving a request to look and touch, and another set in a quiet evening spent together.
