Love Hate relationship? It all started with the introduction of an exchange student who was also her brother's best buddy.

I did not believe that love would struck me when I was 18, in 2013. Looking back at the times I had in school, I was purely studying, studying and studying. My life was nothing special, probably the same as all the high school girls in Seoul. I had crushes occasionally but they would only be crushes and nothing more. I used to admire them from far. However, in summer 2013, an exchange student came crushing into my life. His name is Luhan.

Love? I think that it had died years ago when she broke my heart. I will just go around trying my luck with different girls.

I love her since I first met her. I didn't have the courage to say. I wished I was her reason to smile and laugh.
