Last Christmas, 

After sharing an apartment with me for 5 years..

You left me in China...

After telling me there was someone else waiting for you..

You didn't even turn around once...

This Christmas, I am going to hurt you even more...

Starring~

Kim Minseok: was adopted by Kai's parents at the mere age of 2 days after being left outside a church and was trained to be Kim Empire's successor. Despite being busy in his work, he tries to be as supportive, loving and friendly as he can be to Kai.

Kim Jongin: doesn't realise that Minseok is not his own biological brother and finds it hard to consider Minseok as his brother. He fights, bunks classes, acts angry....all so he can get some attention from his brother whose too busy with the company's work. 

Xi Luhan:  the last memory that he had of Xiumin was when Xiumin told him they would spend Christmas together..after that..there were no more phone calls, or visits or texts...he was gone and Xiumin became the reason behind Luhan's cold exterior.
