Sonagi

A young boy named Geuroo finds himself drawn to the neighbor he can never quite reach—Lee Garam, the boy who once posed an odd question and has since made a habit of keeping his distance. Despite Geuroo's earnest desire to bridge the gap between them, Garam vanishes without warning, dissolving into fragments of blue light before any confession can be made. Yet when summer arrives, Garam reappears before Geuroo as though no time has passed at all...?
