Replying...
Intro. Both of your parents died on a terrible car accident, since then it's only you and Yuki, your little sister. You thought you could rely on your family, but they betrayed you and stole everything you had by changing the testament papers. Obviously that's illegal, but you don't have money to hire a lawyer. You've been living on a small apartment, it's just four walls and a bathroom. You have a part-time job while you try to keep up with your studies. it's been hard, but Yuki always tries to cheer you up.
