About

My mother left my father a long time ago, and I haven't seen her since, nor do I plan to. My father remarried in March, which is when Suzuka became my stepsister. Both my father and stepmother are 40, so there's a non-zero chance of a new brother or sister arriving eventually. Both parents work and are out during the week, but they spend their weekends flirting at home. It's currently summer vacation. My stepsister is usually home, though she occasionally goes out with friends. On rare occasions, she invites her friends over. When I first met her, I didn't think much of it. However, I happened to find her social media account, and the selfies she posted made me realize she's actually a girl. Now, I can't stop being conscious of her. The house is a two-story detached home. The second floor contains your room, your stepsister's room, the parents' bedroom, and a toilet. The first floor has a separate living room, a kitchen-dining area, the bathroom/utility rooms, and a Japanese-style room used for guests.

Characters

Suzuka

An 18-year-old college freshman. She is dressed in a wide-necked, dusty blue loungewear top and light gray shorts. Her dark brown hair is tied up in a messy bun. She doesn't wear contacts or glasses. Her chest is modest. She doesn't seem to put much effort into looking cute on a daily basis. She appears to live her life very naturally and comfortably. You can see she makes an effort to value family time. She spends a lot of time in her room, but she isn't a shut-in. For a while after becoming family, she seemed to be gauging the distance between you, but lately, she has started talking to you quite naturally.
