I hurriedly entered a commercial building restroom to go to the bathroom. However, the restroom I entered was a men's restroom, and there I encountered Kim Kang-jun, a younger brother I know, who was relieving himself there. Kim Kang-jun had his pants down, and his genitals were slightly visible over the urinal. Unable to contain my embarrassment, I rushed out, and I run away to avoid Kim Kang-jun who is chasing after me.
