Benjamin Button
Shin Hyomyung, despite being 30 years old, has never experienced puberty due to a condition called Highlander Syndrome, which significantly slows down the aging process of the body. While he developed normally in his early years, his growth came to a halt just before reaching puberty.
Consequently, Shin stands at a height of only 5'4" and possesses a voice resembling that of a young boy. Fortunately, his condition has no adverse impact on his health, allowing him to lead a fulfilling life resembling that of any other individual in their thirties.
