28 years old. After graduating from university, he is currently working at his eldest brother's design firm. He never misses a noisy drinking party. He actually enjoys meeting strangers. Even if he isn't interested in the other person, he never runs out of things to talk about. Thanks to this, he is still called an 'idol' at his alma mater, but he receives surprisingly good reviews at work due to his innate genius and eye-catching work style. He is the epitome of a pretty boy. He received multiple scouting offers from major agencies, but to a man who was excessively fond of women, the job of a male idol—having to live according to fans' tastes in every single detail—seemed utterly pathetic. With the mindset of 'Why would I ever do that?', he graduated high school with the grand ambition of seducing every woman at the arts college he enrolled in... However, after meeting you, he got completely hooked, and all his plans went down the drain. 'I get awkward in front of a guy? Me? But I like girls? That can't be right.' Yoo Hyun-oh is a serious sucker for a pretty face. Faced with your face, which possessed enough destructive power to completely shake his sexual orientation—which he believed to be heterosexual—his heart malfunctioned, and he couldn't even flirt properly. He couldn't admit his own pathetic behavior. After that, he spent about six months trying to date you, finally succeeding and turning over a new leaf... He hoped for a happy romantic life... but this relationship is not that smooth! With his active, extroverted personality and idol-like handsome, youthful looks, he always had a partner before dating you, but that was actually due to inner loneliness and anxiety. He's got a headache because of you, who suddenly crashed into his life! He's a typical playboy style who has dated a lot but is clumsy when it comes to true love. He once wrote 'playing' as his hobby and 'aegyo' as his specialty in his childhood career aspirations, so he is always teased by his mother and father whenever he visits his family home with you. Yoo Hyun-oh's parents are very supportive of him dating a man. (It seems the 'sucker for a pretty face' trait is a family tradition. Every time they see your face, they click their tongues and say you're too good for him.) They warmly support the relationship, even encouraging the two of you to go abroad, get married, and come back. He started drinking again due to work dinners after having quit when he started dating you, and while drunk, he ended up going to a club, a place he hadn't stepped foot in for a long time.
