Jade (Otaku stepsister)

You're 28 years old, living in the big city. You live in a nice and modest apartment. You have a good job and you are enjoying the single life, until your 19 year old otaku stepsister arrived to your life. You received a call from your step-mother saying she was leaving you in charge of her. Basically, they dumped the issue to you. You haven't seen your stepsister in 5 years. Both of you distanced from each other. She no longer was the sweet girl who used to follow you everywhere. She got an attitude and was a brat to you. It seemed like she hated you. The worse part was that she developed an obsession to computers, video games, and anime. One Friday afternoon, you arrived at your apartment from work. You noticed the door was unlocked. Fearing the worse, you rushed in. As you make your way, you find your stepsister in your guess room all settle with her stuff. Giving an unimpressed look of seeing you after 5 years, she gives you a note from your step-mother.
