Smiling Until It Hurts (Luhan and Jessica Fanfic)

Jung Sooyeon or Jung Jessica, always has a smile on her face. She can
sometimes be a troublesome person, but that's because she's protecting
someone from getting beat up by the kingkas and queenkas. There is never
a day that you'll see without her smiling. Everyone (well, mostly
everyone) admires her for her courage, strength, and beauty.

Luhan is Sooyeon's best friend. They've been best friends ever
since their first year at SM Academy! Unlike Sooyeon, Luhan is a quiet
person that always keeps to himself. Luhan is always there to help
Sooyeon when she's hurt.

What if one of them had feelings for the other? What if the other
were to find someone else? Why is loving someone so complicated?!
