So when he suddenly wakes up seven years in the past-just one month before starting high school-he’s stunned. Now, with a second chance, Haibara is determined to rewrite his past. Can he avoid his old mistakes, climb the social ladder, and finally win over his dream girl? Or will he end up repeating history as the school’s biggest outcast? Armed with workout routines, online advice, a loyal childhood friend, and sheer determination, Haibara is ready to face his teenage years again-this time, on his own terms.
