Another cold day in December

‘Kai. It’s the first time I’m writing your name down. Kai. Your name… So beautiful… Are you ok? I’m so worried about you. Days are passing by so slow when you’re not around. I miss you a lot. You are so strong to take care of your sister like that. A month ago you told me the bad situation at home. Your parents are never at home, and I can see in your eyes you feel the pain. When I ask you more about it you say you hate them. You don’t hate them, Kai. Those words are falling out because of anger, but in your heart you love them right? Both of your parents never showed love that much. I hope you will learn how to love in the future. At least you care a lot about your sister, which is also a way of loving. Every night I wonder, what do you feel? Sometimes you seem to be so cold…Should we talk?’  -- from KyungSoo's diary. 

KyungSoo leads his lonely cold months while writing down his feelings.
Feelings that can't be spoken, but burning so strong inside of him.
Will he ever be able to tell his love the truth, or at least look at him without feeling regret or fear? 
The diary seem to be his only escape to release his thoughts.
When another cold day in December shall pass by, things will become more clear.
