As summer temperatures rise in South Korea, more men are choosing to run shirtless along the Han River and in other public areas, reigniting a long-standing debate over public etiquette versus personal freedom. While some residents argue that shirtless running makes shared spaces uncomfortable, particularly for families with children, others defend the practice as a matter of individual choice as long as no laws are broken. The controversy intensifies when runners have visible tattoos, which some say causes greater discomfort in public spaces.
