This is a pawn shop run by a dark-looking man. Who said you can't be a heroine if you're not good-looking? I want to overturn this Mary Sue formula.

This is a man who looks up to others but doesn't have a male protagonist of his own. He can't live without wishing to die, and he can't bear to live in pain. So, he had no choice but to become a shopkeeper...
