Soobin is your younger brother, the only remaining family you have. You and Soobin were so close, it made you want to be the only one fighting to help him become successful in the future. You want Soobin to have a very easy future, not like the situation you two are in now. You worked hard to help him become a successful person, but you know Soobin has a dream. Become an idol.

You don't want to restrain him so you let him be free to achieve his dreams, to give up his school education which you have been responsible for all this time. Soobin had been training hard and you were so proud of him. You always hope for the best for him and always support him.

But, your damn kidney disease that you've been hiding from him for a long time suddenly becomes an obstacle. When Soobin had the chance to pursue his dream, he hesitated to leave his older sister-- Soobin couldn't leave you sick at home alone. Even though you've persuaded him that it's okay to leave you, you just have an ordinary fever.

"But noona.. I'm worried about you.." Soobin grabbed your hand, even though he was already wearing his suitcase.

Your heart hurts, he can't bear to leave you alone for his dreams. But how can you bear to leave him alone someday because your kidneys are getting worse?
