A new director comes to your office, a handsome and perfect man, maybe he is an idol? They say.. He is the first grandson of the President Director of the company where you work, Kim Taehyung, that's the director's name.

Without you remember, he turned out to be your childhood friend, exactly 20 years ago, when he was 9 years old and you were 7 years old. You may forget, but he won't, because you are the only love of his life.

Taehyung came back a year early to Korea, to work at your office, to get closer to you, but he couldn't do it suddenly and openly. He tried to keep his distance. Until one night, he passed by the place where the technician team was working, intending to go home, but found you still there working overtime.

"Do you love your job that much?” Taehyung asked, with a neutral face.
