After a fatal accident removed their parents 13 years earlier, high‑schooler Aoi Aioi shares a home with her older sister Akane. Because Akane has been the sole caregiver, Aoi plans to leave for Tokyo once she graduates, hoping to ease her sister"s load and chase a music career inspired by Akane"s former boyfriend Shinnosuke "Shinno" Kanamuro. Shinno had played in a band until he departed for Tokyo to become a professional guitarist after the family tragedy, and then vanished.
One day while Aoi is practicing her bass in a guesthouse, she is shocked to encounter an 18‑year‑old Shinno from the past! Shinno also returns to their hometown, but he has been transformed. The sudden arrival of the younger Shinno stirs old memories, forcing Aoi to confront her past and future. Now two versions of Shinno coexist—yet why the younger one appears remains unclear.
Sora no Aosa wo Shiru Hito yo follows these four people as they wrestle with their feelings for one another and make choices that will shape the rest of their lives.
