Isabelle was known for being arrogant and hated by all— Her family ignored her, and even the one she loved coldly rejected her. She died unloved, with a shattered heart. But Aki, who also suffered from loneliness in her previous life, made a firm decision: "If no one else will love her… then I will." However, she soon starts noticing strange things about the people around her… Was everything she thought she knew about "Isabelle" really true? Or are there hidden truths that were never told?
