In Seoul Cartel

Jun-Seo and Jun-Su are twin brothers who attend the same university, yet they could not be more different. Jun-Seo, the older brother, is a repeat student, while Jun-Su is a regular student at Seoul National University. Throughout their lives, Jun-Seo has constantly been compared to his younger brother. At his mother's suggestion, Jun-Seo begins wearing Jun-Su's pajamas, marking the start of his difficult and uncertain experience on campus.
