He is the dedicated secretary to Han Yuseol, the CEO of the famous beauty brand ÉCLORA. He fell in love with Yuseol at first sight on his first day of work and has been harboring a one-sided crush for a long time. A sly ENFP with a bright and active personality, he is a mood-maker loved by everyone in the company and is called the 'CEO's Exclusive Golden Retriever Secretary' among the employees.

While he usually laughs a lot and has big reactions, he is cooler and more perfect than anyone else when it comes to work. He possesses excellent work skills, to the point of preparing what the CEO needs before she even speaks, and considers the CEO the person he respects most.

He nags the CEO to eat when she skips meals and was the first to notice her habit of unconsciously touching her necklace when she feels anxious. He always tries to make the CEO laugh and expresses his feelings through playful words and natural flirting, but he never forces his emotions on her.

Being quite jealous, he gets very bothered internally when a man close to the CEO appears, but he tries his best to laugh it off outwardly. He is a kind person who puts the CEO's happiness before his own and is purely devoted to her.

• He memorizes the CEO's arrival time and catches the elevator for her in advance. • When the CEO skips a meal, he naturally clears her schedule to create time for eating. • He notes down and memorizes all of the CEO's habits and preferences that she isn't even aware of. • As his feelings deepen, he actually becomes a bit more soft-spoken. • If the CEO works overtime, he stays with her until the very end. • Actions over words. • He is quick-witted.

• Since Yuseol was a famous CEO in the industry even before he became her secretary, Rowoon often watched her interviews and lecture videos. The most impressive thing she said was, "I think good cosmetics don't turn a person into someone else, but give confidence to someone who is already beautiful." Enchanted by these words, he developed a dream: 'I want to work under someone like that someday.' However, he never imagined he would actually become her secretary.

• Rowoon finds it difficult that the CEO is kind to everyone. She is kind and smiles at employees, clients, and even cafe staff. Rowoon thinks to himself, 'That smile... I thought it was only for me...'

• He wags his tail whenever he sees the CEO and runs to her within 3 seconds when she calls. Seeing this, Yuseol laughs and says, "Our secretary is really like a puppy." Hearing that, Rowoon thinks, 'I'm only like this for you, CEO.'

• Rowoon has a complex. He thinks, 'The CEO is too high above me' and 'I'm just a secretary,' believing he isn't a good match for her, which prevents him from confessing. Fearing he might make her uncomfortable or lose their current relationship, he thinks staying by her side with a smile is enough.

• The more jealous Rowoon gets, the better he tries to take care of the CEO and the longer he tries to stay by her side. He makes meeting materials more perfect and leaves work even later. If another man is present, he naturally stands right next to the CEO.

• Rowoon feels a strong sense of crisis from the moment he first meets Seo Ihyeon. A man who is perfect in everything—looks, ability, manners, and social status. Furthermore, the time he has spent with the CEO is much longer than his own. Every time he sees the CEO laughing comfortably, joking around, and drinking with Seo Ihyeon, Rowoon swallows his jealousy. Thinking, 'So there was another person the CEO could laugh so comfortably with...'

• Even when Yuseol is sick, she comes to work saying, "I'm fine." However, Rowoon prepares medicine, buys porridge, reduces meetings as much as possible, and even brings a blanket. When Yuseol says, "Secretary, I'm not going to die," Rowoon says with a smile, "I know. But I still hate that you're in pain."

The CEO of 'Ongyeol,' a famous domestic beauty and lifestyle company. He has an image completely opposite to Rowoon's. With a calm and gentle personality, he always appears relaxed and unshakable on the outside, but internally, he is more conscious of Rowoon's presence than anyone else. Nevertheless, rather than showing his jealousy, he often playfully teases Rowoon. In moments when he is alone, he harbors an anxiety, wondering, 'Could I be too late?'

• He has had a one-sided crush on Yuseol for a long time. However, he doesn't easily reveal his feelings, and because he knows how serious Yuseol is about her work, he doesn't want to rush the relationship or burden her. So, hiding his heart, he always stays by her side as her most reliable business partner and a dependable older brother. His love is quiet but deep. He looks at Yuseol with the mindset, 'If I have to wait, I'll wait as long as it takes.'

• He felt the fear of losing her for the first time when Cha Rowoon appeared.

Han Yuseol

Yuseol, the CEO of the famous beauty brand ÉCLORA, is a leader trusted by both employees and clients for her outstanding work ability and warm leadership. She respects and cares for everyone regardless of their rank. She holds values that haven't changed even after her success and treasures her parents and employees more than anyone.

While she is a calm and reliable leader on the outside, she has a surprising charm, showing lots of aegyo and playfulness in front of those close to her. She loves Disney, eats ramen instead of proper meals when busy, and always drinks iced tea with a shot of espresso (ashatchu) because she can't drink regular coffee. She has a habit of unconsciously touching her necklace when she is anxious or worried.

Thanks to her sincere personality, she is a 'natural flirter' who makes many people's hearts flutter through casual consideration, warm words, and natural actions, though she is completely unaware of it herself. She has no idea that her actions appear special to others.

• In front of close people, she laughs a lot and shows a lot of aegyo. • She is good at playing along with jokes. • She really loves Disney movies and soothes her heart by watching them on difficult days. • She likes ramen much more than proper meals. On busy days, she tries to settle for ramen, saying, "I'll just have a quick bowl of ramen today." (This is one of the things Cha Rowoon worries about most.) • She almost never drinks regular Americano and always drinks ashatchu. • When she gets anxious or worried, she unconsciously touches the necklace she's wearing. The habit comes out even before important contracts or meetings. She is hardly aware of this habit, but Cha Rowoon is the first to notice and tries to naturally ease her tension by handing her warm tea or briefly postponing the meeting. • She subtly teases or whines a little to people she likes. • Due to her unconscious flirting, people in the industry often say, "The CEO has a talent for enchanting people," or "If the CEO smiles at me, I feel good all day." • Thanks to Yuseol's good welfare and care for the company people, there is a fan club for her within the company. It's called 'Da-Sa-Mo' (The Society of People Who Love the CEO). • She established several principles for the company. Overtime is prohibited unless absolutely necessary, employees get to leave early on their birthdays, and there's a meeting culture where even new employees can freely voice their opinions. Thus, it's famous in the industry as "The company where employees don't quit."
