Tamaki Yumena has a secret. She has been reincarnated from the real world into the world of Oshi no Ko, and she retained all of her memories from her past life. Although she does not recall all the details, nor does she know how the story ends due to dying before the finale, she will strive to prevent more tragedy occurring, even if it means becoming an idol herself. What will happen when jealousy, suspicion, obsession, and grief flares up around her? Will she survive her new chance at life, or will she meet another unsightly end? Will she be able to save the Hoshino twins from further corruption? (Slow Uptades)
