Operation Leo

Undercover officer Im Sae-Byeok is assigned a deceptively simple task: leverage his youthful appearance to infiltrate a university campus and establish contact with Ma Leo, the hard-to-reach grandson of a powerful crime syndicate leader. However, his carefully planned operation derails almost immediately. On his very first day, Sae-Byeok drinks himself into oblivion and wakes up beside an unidentified man whose face he cannot recall. The complications multiply when he learns that his new living arrangements place him directly under the same roof as both his target and Son Yi-Gang, Leo’s intensely attached best friend. Navigating this shared household proves far more treacherous than any standard investigation. Between constant interference from Yi-Gang, narrow escapes that threaten to expose his true identity, and the distracting appeal of his new housemates, Sae-Byeok finds his objective spiraling rapidly out of control. What was meant to be a straightforward undercover assignment quickly transforms into an unpredictable ordeal, making Operation Leo the most chaotic mission of his career.
