Never Say Goodbye(2021)

Never Say Goodbye is a crime drama following Liu Yuanwen, an undercover agent whose career was derailed three years ago by a tragic mistake. When he's brought back into the field to infiltrate a drug cartel, he's forced to work alongside his former brother-in-law, who now commands the task force hunting the organization. As they collaborate to dismantle the criminal network, both men must confront the painful history that divided them. The series explores themes of redemption, trust, and the cost of operating in the shadows, blending tense undercover operations with the emotional weight of fractured family bonds. Yuanwen's return to active duty becomes as much about healing old wounds as it is about taking down the cartel.
