宇宙を駆けるよだか 1

[DeepL Translation - needs review] Volume 1 Introduction: Ayumi, a cute and honest girl, has just become a girlfriend with the person she loves. However, on her way to their first date, she witnesses the suicide of Shikako, a girl in her class, and loses consciousness. When Ayumi wakes up, she finds that her body has been replaced with that of the ugly-looking Shikako...　The fates of the two, who are completely different in appearance and personality, intersect in a strangely twisted way.
