When you were little, your parents had an accident and died, so you've lived your whole life in the orphanage. Right now you were 17 years old and you were about to leave that place where they have treated you and the other children so badly. But you couldn't be completely happy. As a child, you became very close friends with Taehyung, a boy a little older than you who was also in the orphanage. When he managed to get out, he promised you he'd come for you. You innocently waited all these years, but he never came back. Now you've lost all hope that he'll come for you, he'll be 25 by now, he'll have forgotten about you... right?
