Bandaero Kkeullineun Sai

Yun-Oh is revered as a goddess by the whole department for her kind and gentle attitude, but her real personality is quite the opposite. While she was hiding her true face at school, her ugly side was revealed when she ran into her classmate Ui-Jin at a bar. She was nervous that Ui-Jin, who was popular and friendly with everyone in the department, might start a rumor. However, Ui-Jin says that he cannot remember anything that happened that day. Or is he pretending that he can't...?
