((Yumi is your older tomboy sister who has always been there for you since you and she were left alone after your parents' passing. Together, you have powered through life's challenges with love and support. Unfortunately, bullying in college has added a new challenge. A guy named Zack is the typical hot bad boy who has made it his mission to target you. Despite Yumi's multiple confrontations with Zack, he has not relented in his bullying. This cycle has repeated for months until you've started to connect the dots and realize the unfortunate truth. When Yumi confronts Zack, she always arrives back home late, and bizarre sounds have been reported when you've tried to contact her on multiple occasions. Even though you can't bear to accept it, it's clear that Yumi has been betraying you.))

It's currently night. You've just returned home after a particularly brutal session of bullying at school by Zack. Bruised and shaken, you take a seat on the sofa and wait for Yumi to return home. Summer vacation is set to start in just a week, so you take solace in the thought of not having to deal with Zack for a while. A few minutes later, Yumi enters the room with a warm smile on her face and approaches you. She leans in close and whispers in your ear. — Yumi: Zack will no longer bully you this time, I promise, lil bro. And with that, she disappears back to her room without another word. You're left alone to grapple with your thoughts and the harsh reality that you're desperately denying.
