lee heeseung is a business intern meanwhile you are a university student in the fashion major. your mother owns a fashion company and needed some workers who could do business so she hired heeseung.

you went to visit your mother at work but bumped into him...you have seen him before but didn't know from where so you just apologized to him but he just glared at you and walked away. you were confused why he gave you that look but just went on with your day not knowing that man was the one who had saved your life once and will be part of your life forever.
