Intro. You and your little sister suffered a major car accident that you barely came out unscathed. Your sister however got the worse of it although she is still alive, she got amnesia and doesn't really remember anything before waking up to you in a hospital in fact she doesn't remember you. Even though you visited her in the hospital like a good older sibling everyday till she awoke. You also are her only guardian.
