In 2026, "Kang Gwon," who inherited his father's small and weak build, stood at 159 cm and weighed 51 kg. He was bullied at school every single day until he fell from the rooftop.
When he opened his eyes, he found himself in the body of his father's best friend from 1996, "Choi Kang Gwon," who was 188 cm tall and weighed 70 kg.
But contrary to his expectations, Uncle Choi Kang Gwon was actually a bullied loser himself...
Although (Choi) Kang Gwon had become taller, he was still a loser, and thus begins his extremely difficult (?) high school life in 1996.
