I absolutely love this series and would easily give it a 5-star rating. This book is packed with excitement, from the introduction of Ai to a shocking murder and the unexpected rebirth of two characters as the babies of a renowned Idol, AI, who tragically falls victim to a crazed fan. The premise for "Oshi No Ko" is undeniably unique. It revolves around an OBGYN who stumbles upon Ai Hoshino, a rising idol, through a former patient. As a devoted fan, he's taken aback when she seeks his help. What follows is an incredibly unconventional reincarnation story that pushes boundaries, yet it also exudes heartfelt emotion and genuine sadness. The ending of the first volume truly caught me off guard and tugged at my heartstrings. Now, there's potential for an incredible revenge plot that I'm eagerly anticipating.
