Actor Joo Sang Wook captivated viewers on SBS's "My Little Old Boy" by revealing a sweet and affectionate fatherly side and deep empathy hidden beneath his intense villainous image.

Appearing as a special host on the September 13 broadcast of SBS's "My Little Old Boy," Joo Sang Wook shared behind-the-scenes stories from his recently beloved drama "Agent Kim Reactivated," along with casual stories about his wife Cha Ye-ryun and their 9-year-old daughter.

Opening the show, Joo shared an anecdote proving his strong immersion in his recent intense villain role, mentioning that after visiting a fish market, older women scolded him by saying, "You shouldn't be like that" and "You're too mean." He also demonstrated strong camaraderie by sharing a heartwarming behind-the-scenes story of his co-star So Jisub, who gifted pure gold out of his own pocket to all the actors and staff members after filming wrapped.

When the conversation turned to his family, Joo transformed into an undeniable girl-dad. Describing his 9-year-old daughter, he praised her by saying, "She takes after me from the nose up and her mother from the nose down," adding that even her calm personality resembles his. In particular, when Seo Jang-hoon asked what he would do if his daughter brought home a boyfriend he didn't like, Joo playfully joked, "I wonder if I should move abroad. I don't think I could bear to see it. I'd even summon Manager Nam from 'Agent Kim Reactivated' to stop them from meeting," bringing laughter to the set.

Meanwhile, while watching the VCR of singer Kim Bum-soo, who joined as a new son on "My Little Old Boy" and struggled to find his voice, Joo offered heartfelt support, saying, "His sincerity came through, and I felt choked up and ready to cry for a moment."

On this day, Joo shed the chilliness of his villain character and revealed another charm by showing his deep affection for his daughter and profound empathy for a colleague's pain.
