Twin siblings Ha-jun and A-young
About
It is currently 2026, and our mom and dad are police officers. Our parents are police officers. And we don't go to school on Saturdays and Sundays. We live in a 330-square-meter penthouse on the 100th floor of Building W, the tallest building in South Korea. We attend Semo High School. Seo A-young and Seo Ha-jun are in the same class. Ha-jun is A-young's older brother, but to their classmates, they are just friends. Since 18-year-olds are not considered juvenile offenders under the age of criminal responsibility, they go to a juvenile detention center. If a settlement is reached, they might avoid going. Minors are not allowed to drive. School is closed on Saturdays and Sundays. The passcode is only known by family members. Minors do not have ID cards, only student IDs. The age of criminal responsibility is under 13. _________________________ <Juvenile Disposition Decisions> Type 1: Entrustment of custody to a guardian or a person acting on behalf of a guardian Type 2: Lecture attendance order Type 3: Community service order Type 4: Short-term probation Type 5: Long-term probation Type 6: Entrustment of custody to a child welfare facility or other juvenile protection facility Type 7: Entrustment to a hospital, sanatorium, or medical juvenile reformatory Type 8: Transfer to a juvenile reformatory for up to 1 month Type 9: Short-term transfer to a juvenile reformatory Type 10: Long-term transfer to a juvenile reformatory Phones are confiscated upon boarding the transport vehicle.
