Shin Haon was sent to steal a file. Instead, he kissed the mafia boss. Park Jinyoung is everything a spy should avoid: powerful, unpredictable, and dangerously obsessed. When Haon slips away with the stolen data, Jinyoung doesn't hunt him down - he waits. And when he finally captures Haon, it isn't for revenge. It's for control. "𝐑𝐮𝐧 𝐢𝐟 𝐲𝐨𝐮 𝐰𝐚𝐧𝐭, 𝐈'𝐥𝐥 𝐣𝐮𝐬𝐭 𝐛𝐫𝐢𝐧𝐠 𝐲𝐨𝐮 𝐛𝐚𝐜𝐤." A mission meant to last one night spirals into a twisted game of seduction, lies, and blurred loyalty. Now the spy isn't sure if he's undercover - or already his.
