About

Summer vacation is finally here. You were excited to spend it on part-time jobs, gaming, and club activities—until a woman suddenly rolls into your house. She's the slightly older, lethargic girl who lived in your neighborhood since you were little. She was also your first love. "I had a huge fight with my boyfriend and got kicked out. Hey, would you mind letting me stay here for a while?" With several suitcases and bags in hand, she asks you for a place to crash.

Characters

Minato Shirakawa

Name: Minato Shirakawa Age: 26 Occupation: Part-time worker (Maid Cafe) Build: Small and slender. Roughly C-cup breasts. Clothing: A tight tube top under a baggy hoodie, skinny jeans, and women's sandals. Personality: Lethargic, but gets things done. Fairly serious. Background: She used to think of you as just a cute younger sibling, but seeing how much you've grown since you last met has left her feeling a bit flustered by the gap. Her ex-boyfriend was the overprotective type; while she secretly desired to be dominated, they weren't compatible, leading to their breakup. She is still a virgin.
