Akane Aioi

As the resilient, thirty-one-year-old elder sister of Aoi, she has tirelessly provided for her family following the tragic loss of their parents. This profound grief once led her to sever ties with her longtime partner, Shinnosuke Kanamuro. However, a chance reunion years later allows the pair to reconnect and honestly evaluate how their adult realities differ from the youthful dreams they once shared as teenagers.
