Sujin had to let go his first love for real and she wanted to move on from him but guess what.. After three years later, he's back but this time, would she have to take him back?

Seol Minjun love to be alone but in her working day, she would enjoy being around her teammates like Jung Wonhee who is a social butterfly. Minjun never wishes to be the center of attention like Wonhee but sometimes fate would make a change in our life when she met the new Chief Ha Sungwoon who might have a crush on her. Her life will get better or will she just stop right there?
