Shinichirou Niihama’s body and spirit were pushed to the breaking point by a ruthless corporation, ultimately causing him to collapse from exhaustion. When he opens his eyes again, he is no longer a broken salaryman but a second-year high school student reliving his youth. His original high school years were bleak and miserable, yet now, armed with the wisdom and experience of an adult, he realizes he has been granted a miraculous opportunity to rewrite his past. This chance for redemption takes on deeper meaning when he reunites with Haruka Shijouin, a beautiful girl from his previous life who now appears even more radiant and pure than he remembers. Unlike others, she looks directly at him and notices the profound change in his demeanor, observing that he seems remarkably mature while still retaining his fundamental kindness. Her words ignite a fierce resolve within him, because Shinichirou knows her tragic fate: in the original timeline, severe bullying drove her to death. Determined to alter the future, he vows to protect Haruka at all costs. Leveraging his adult mentality and the shrewd skills he honed in the corporate world, Shinichirou sets out to exact revenge on those who wronged them. Together, they will reclaim his lost adolescence, transforming a once-dark past into the ultimate second youth.
