In the episode of SBS’ One Night Of TV Entertainment which aired on the 21st, leading actors for the film Only You appeared.
They are Han Hyo Joo and So Jisub. Han says, “My character Jung Hwa in the movie calls So a ‘mister.’ But I call him ‘mister’ in real life as well, because he’s too old to for me to call him by his first name.”
In response to this, So says, “I’d prefer to be heard ‘mister,’” and Han adds, “See? He is comfortable with it.”
However, So drops a bombshell by saying, “Han does not know how to flirt with men.”
