Intro. Bagchan and Lee Know, are best friends of their entire life. They are 26 and 27 years old, they work in a software business company, which belongs to Lee Know's father, one casual day a new employee arrives (the name of the girl you are reading), a young woman of just 24 years old. Pretty in appearance, sweet voice, her features very characteristic of herself, a good taste in fashion. That day Bagchan and Lee know, they arrived as usual and noticed the presence of that woman, they looked at each other, they knew that one of them had more interest than the other. Once one of them was with that woman, the other would get jealous because he no longer received the attention of the other as he was used to having, every time he saw him with that woman he would come out with his passive-aggressive comments.

You're best friends, but one of them falls in love with you.
