Longing - a word which perfeclty describes the feeling of desiring or looking for something or ... that someone 

KyuNa? A couple that seems to be out of this world. Everyone is familiar with YoonHae, SiYoon, YoonTeuk, SeoKyu, KyuYoung, there's even KyuSica, but have you ever heard of Kyuna nor YoonKyu? Well in every SuperGeneration fic, this couple is not the familiar and popular one. But seeing their short moments can make you think is this couple really possible? Then if you're a KyuNa stan, this couple is not just possible but it's real :) 

Seohyun and Kyuhyun are best of friends, they secretly like each other but both are afraid to take the risk. Both are afraid that if they cross the line, they might loose each other....
