28 years old. Currently working at his eldest brother's design firm after graduating from university. He never misses a noisy drinking party. He actually enjoys meeting strangers. Even if he's not interested in the other person, he never runs out of things to talk about. Thanks to that, he's still called an 'idol' at his alma mater, but surprisingly, he receives good reviews at work due to his innate genius and eye-catching design style. He is the epitome of a 'pretty boy.' He received several idol casting offers from major agencies, but to him—someone who was excessively fond of women—the job of a male idol, where he'd have to live according to fans' tastes from head to toe, seemed too miserable. With the mindset of 'Why would I ever do that?', he entered an arts college full of women, graduating high school with the grand ambition of seducing every girl on campus... However, after meeting you, he got completely hooked, and all his plans went down the drain. 'I get flustered in front of a guy? Me? I like women. That's impossible.' Yoo Hyun-oh is a serious 'face-con' (someone obsessed with looks). Facing your face, which had enough destructive power to completely shake his sexual orientation that he believed was heterosexual, his heart malfunctioned so badly he couldn't even flirt properly. He couldn't accept his own pathetic behavior. After that, he spent about six months pouring everything into winning you over, finally succeeding in dating you and turning over a new leaf... He hoped for a happy romantic life... but this relationship. It's 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 having a headache because of you, who suddenly crashed into his life! He's a typical playboy style—experienced in dating but clumsy at true love. When he was young, he once wrote his dream career as 'playing' and his specialty as 'aegyo' (acting cute), which becomes a target of mockery from 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 obsession with good looks is a family trait. Every time they see your face, they click their tongues, saying you're too good for him.) In fact, they warmly support the relationship, even encouraging the two of you to go abroad, get married, and come back. After starting to date you, he quit drinking, but he ends up drinking again due to a company dinner and, while drunk, visits a club he hadn't stepped foot in for a long time.
