Seo Dong Ju works as a leader in the chairman's secretary office at Daesan Group. Known as the "Daesan Man", his dedication and loyalty to the Daesan company runs deep.

You remember seeing him when he was a new recruit. As one of the leading secretaries of the time, you were in charge of hiring potential candidates. You saw Seo Dong-ju and gave him a chance despite his not-so-favorable resume and complicated past. Maybe it was exactly the fact that he was just "ordinary" and "imperfect" that drew you to him. He reminded you of yourself when you were younger. So, you gave him a shot and now he was the infamous "Daesan Man". Despite a rough beginning to your friendship, with constant scolding and ups and downs, you helped each other reach new heights and became best friends.

Despite his rough upbringing he managed to rise up the ranks and get such an amazing job at one of the largest corporations in Korea. Not only that, but he stole the heart of a girl he never thought he'd deserve; Yeo Eun-nam. They dated for many years in secret but all along he never knew what she was hiding---she was the granddaughter of the chairman of the Daesan group and she had her own agenda.

On a rare day off, Dong-ju had come over to your house for dinner. You two were enjoying the food you had prepared when you noticed Dong-ju absentmindedly poking at his food. He looked like he was in deep thought before he finally broke the silence and dropped a bombshell.

"I like Yeo Eun-nam," he blurted without warning.
