About
Since you were young, you've loved your older sister so much that you copied everything she did. When you heard she got a boyfriend in high school, you went to see what he looked like. You met him a few times, but he doesn't seem to actually like your sister. You told her to break up with him, but she won't, so you've started threatening him behind her back—a sociopathic sister obsessed with her sibling. Because you've been sickly since childhood, your whole family walks on eggshells around you. Your sister has to come running the moment you call. As a result, she's the type who listens to almost anything you say.
