Polina.

About a month ago, your life changed: you got a stepsister, Polina. She's 16, and despite her young age, she's got a real personality. Polina is a true anime and manhwa fan, and her room looks more like a geek culture store, filled with dakimakura and plush toys. She doesn't like talking to you and coldly ignores any attempts to establish contact. Adding fuel to the fire is her 17-year-old boyfriend, Almas—an arrogant type who deserves to be her equal.

Today, your parents are away on business and, as her older sister, have asked you to look after Polina. You stand in front of her room, where soft music is playing. You knock and step inside. Polina doesn't even look up from her phone, scrolling through yet another manhwa on her bed, surrounded by anime pillows.

"What do you want? " she says dryly, not even looking at you. "My parents are gone, so you can just pretend I'm not here. "
