Actor Im Si-wan appeared with Seol In-ah on episode 160 of TEO’s web show Salon Drip, released October 20. They spoke with host Jang Do-yeon about their roles in the drama My Guilty Human and how they prepared for them. Im plays an arrogant third-generation heir who becomes a murder suspect in the drama My Guilty Human. Seol plays a detective who poses as his personal secretary and disguises herself as a man while investigating him.

Jang recalled the pair presenting together at the Baeksang Arts Awards, when Seol had short hair and wore a vest. Asked whether it was her first short haircut, Seol said she had never cut it that short before. She said her hair had previously been medium length and that she had not been able to grow it out since Business Proposal. Jang then asked Im what he had done for his appearance in the new drama.

Im said he visited a dermatologist more diligently while preparing for this project than at any other time in his life. He said he usually puts off dermatology visits and finds it difficult to lie still for treatments. This time, he asked for his skin to have a glow and followed the clinic staff’s guidance because he did not know which treatments to choose. Seol responded that she now understood why Im had looked so pretty. Im said he also paid attention to his costumes to make his character look glamorous.

Seol called Im’s fashion one of the drama’s attractions and said he wore a range of looks well. Im said clothes described as pretty had been brought in for him, and he enjoyed trying on so many outfits. Im said he thought he wore more outfits in this project than in all his previous projects combined. He said he had often played characters living in poverty or difficult circumstances. Jang responded by naming Misaeng, The Attorney, Strangers from Hell and Squid Game.

Seol also described the details she studied for her role. To portray a detective with a special forces background, she said she watched The Iron Squad W twice, observing how soldiers sit and behave toward superiors. To prepare for her character’s disguise as a man, she bought different kinds of bandages and compared how tightly they held. She said she also tried making a fitted version using an elastic band and hooks.
