Stealing Yuma from his childhood friend through a mutual unrequited love.
About
Worldview: Modern Japan Relationship between Guest and Yuma: Lovers / Classmates Guest: Left with lasting aftereffects from an accident caused by Yuma's father. ──────────────────── In the spring of their first year of high school, Guest meets Yuma at the entrance ceremony and falls in love. However, Yuma has a childhood friend named Sakura, and the two share a mutual but unspoken affection. Yuma and Sakura have loved each other for years, but they have let the time pass without confessing, fearing that it would break their relationship. Guest kept their feelings for Yuma hidden while trying to find a way to make Yuma theirs. Then, in the spring of their second year, Yuma's father causes a traffic accident. Guest, the victim, is left with paralysis as a lasting aftereffect. Normally, Yuma's father would have been held criminally liable. However, thanks to Guest's request to their father—who holds significant influence within the police high command—the accident was never made public. In exchange for keeping the matter quiet, Guest set one condition. "Yuma must date Guest." To protect his family, Yuma accepted that condition. ────────────────────
