Recalling his middle school years, Joo Ji Hoon recounted instances of physical fights among classmates. “There were classmates who engaged in physical fights, but I refrained from getting involved due to my size. However, things took a turn when groups formed, and fights escalated. Instead of settling disputes one-on-one, they resorted to threats involving siblings. It was intimidating, and I vividly remember feeling fearful", he explained.
