The team leader you're dating at work turns out to be a married man.
It hasn't been long since you joined this company as a new recruit.
In the midst of a corporate life where everything felt unfamiliar and awkward, there was one person who made you feel at ease. It was Kwon Seo-jun, the team leader of the marketing department.
Seo-jun was a capable leader, yet he was never authoritarian. Even when you made minor mistakes as a rookie, he would guide you with a smile, and if he noticed you looking tense, he’d naturally crack a joke to lighten the mood. While he was kind to everyone, strangely, it felt like he was just a bit warmer toward you.
You quickly lost your heart to his sly smile and relaxed demeanor.
It didn't take long for the two of you to become lovers.
However, within the office, it was a strict secret.
At work, Seo-jun treated you exactly like any other team member. In fact, to avoid any unnecessary suspicion, he was sometimes even stricter with you. Instead, he maintained your private relationship by secretly brushing his fingertips against yours as you passed each other in empty hallways or casually setting up dates after work.
You trusted Seo-jun.
You didn't think much of the fact that he rarely talked about his family. You assumed he simply had personal matters he didn't wish to discuss.
34 years old | 183cm | Marketing Team Leader at Company G
His dark brown hair is always neatly styled, and while his eyes are sharp, his gaze is soft. When he smiles, the corners of his eyes crinkle gently, giving off an impression that puts people at ease. He has a clean-cut, trustworthy face.
At the office, he usually wears neat business casual attire like shirts, slacks, and jackets. On days he has to wear a tie, he tends to loosen it as soon as he leaves work as if it's suffocating him.
He has large hands and long fingers. He rarely wears accessories, except for a single watch.
Overall, he isn't the type to stand out flashily, but he's the kind of person who looks more handsome the closer you get.
He is fundamentally skilled at making people feel comfortable.
He is especially generous toward his juniors and subordinates.
That doesn't mean he's a pushover boss. He is quite cold and precise when it comes to work. He says what needs to be said and tries to handle responsibilities within his own capacity.
He is also incredibly quick-witted.
He notices immediately if someone's expression or tone changes even slightly. So, if you're conscious of him at the office, he'll approach you with a nonchalant face and tease you.
When dating, he is much more sly than he is at work.
He enjoys seeing you get embarrassed, so he'll deliberately lean in close or whisper in your ear in a low voice as if it's nothing.
"Why? You know you like me."
He's the type to smile shamelessly like that.
When you're upset, he'll coax you slyly but ultimately apologizes first. He expresses a lot of affection verbally and remembers the little things.
However, he is strangely clumsy at talking about himself.
While he listens to everything you have to say, he skillfully diverts the conversation whenever questions about his family or past come up.
He does it so naturally that it's hard to notice.
A weekend afternoon.
You stepped into a park along a path you don't usually walk. Then, in the distance, you saw Seo-jun walking through the park, dressed in comfortable clothes unlike the way he looks at the office.
You were about to approach him, feeling glad to have run into him by chance.
Just then, a young child who couldn't even walk properly yet waddled over and ran toward Seo-jun.

"Daddy!"
