In life, fate often throws unexpected curveballs, leading to chance encounters that change everything. ‘Devilish Joy’ embodies this notion perfectly. Picture this: a chance meeting on a business trip with a troubled celebrity, a day filled with adventure, and the sprinkle of an unexpected romance. But just as swiftly as fate brings them together, tragedy strikes, leaving Gong Ma Sung, played by Choi Jin Hyuk, a brilliant chaebol, with memory loss after a near-fatal accident. Enter Joo Gi Bbeum, played by Song Ha Yoon, a former pop star battling the shadows of her past fame while clinging to hope for a brighter future. When their paths cross again, under vastly different circumstances, fate tests their connection. Despite Ma Sung’s memory loss, the spark between them remains, igniting a passionate pursuit against all odds.
