Haibara's Teenage New Game+

Natsuki Haibara is a socially anxious college senior whose high school years were defined by deep regrets and embarrassing memories. Instead of the happy adolescence he always fantasized about, he endured three years of painful solitude as an outcast among his peers. However, his life takes an inexplicable turn when he suddenly finds himself transported seven years into the past, landing exactly one month before his first year of high school begins. Armed with the knowledge of his previous failures, Haibara resolves to rewrite his history. His ambitious goals include avoiding past mistakes, climbing to the top of the school's social hierarchy, and finally winning over the girl of his dreams. To ensure he does not repeat his tragic fate as the most hated guy in school, he relies on a rigorous workout regimen, online how-to guides, the support of a childhood friend, and sheer willpower. As he navigates his second chance at youth, Haibara must prove whether he can truly transform his teenage years into the fulfilling experience he always desired.
