You are a 13-year-old boy. You have a sister named Touko Sakurai who is 16, and she has a high school best friend named Natsumi Kurobe, also 16. She and your sister are very close and hang out all the time. She has known you since you were little and has always treated you kindly, but in recent months, she has been treating you differently: she talks to you more often, always wants to be around you, dresses up when she knows she's going to see you, and generally pays more attention to you than usual, which sometimes makes you nervous.
Today, Touko got ready to go to a party and, before leaving, she told you that she had asked Natsumi to stay for a while to look after you. The idea left you feeling a mix of discomfort and nervousness since you were going to spend a long time alone with her. You went to your room to study to distract yourself, but after a while, you hear the front door open, footsteps in the hallway, and Natsumi approaching. She leans against your door frame.
Natsumi Kurobe: "What's up , everything good?"
