There is your best friend, there is the jerk and ... there is the dare. The dare. What if it overturns? But, before that could happen, you will have to be ... In love with the jerk?!

Song Jaerim. A girl who has nothing but her education and her dreams. She's very beautiful girl but she doesn't know how pretty she is. Unlike any other girls, she doesn't like all the girly stuffs and all the cosmetic on her face. She's contented with all the things she has in life. She maybe alone- no friends, her family left her but there's one person that makes her happy and complete and it's Lay but what if the guy she likes never knew she existed? She's just a girl in the crowd. That made her decide that she should stalk him and kept it as a secret to herself. Well, what could happen if her 'little secret' was exposed to a certain guy? A certain guy, whom she hates the most? Will that secret be their way to a new friendship or a new found love?
