Kyuhyun, this egocentric and lonely guy. Sungmin, this strange and shy boy. Two painful pasts confront, two frightfully different tempers meet. Nothing was supposed to gather them, apart maybe from the destiny. This playful and selfish destiny. Because to love and to be loved, that's all. That is the rule. That is why we exist.
