It's impossible to break a diamond with only your bare hands.

Sulhee is similar to a diamond, cold and hard to understand. 
She only gives in to people who are important to her life, her brother and her bestfriend - That's why people other than them tend to avoid her, since she's inscrutable. - Until one day, something life changing will happen to her.

 - What will happen to Sulhee?
