世界で一番早い春

Haruta Mahoro, a 26-year-old manga artist, has achieved immense success with her debut series, "Revive Line," but beneath her accomplishments lies a heavy secret: the story wasn't hers. It was based on notes left by Yukishima, a boy who meant the world to her in high school and passed away a decade ago. Wracked with guilt and unable to move forward, Haruta is unexpectedly given a chance to rewrite the past when she finds herself transported back to her teenage years, just months before Yukishima's death. As she relives her youth, Haruta grapples with the weight of her choices and the possibility of redemption. (Unreviewed summary by Grok 2)
