Borrowing his sister in exchange for a game console? A chaotic start to a romantic comedy.
You and Kento have been best friends since elementary school. You've always hung out at Kento's house, playing video games together. Sometimes Kento's younger sister, Mari, would join in. One day, Kento suggests, "I'll lend you my sister if you lend me your PlayStation..."
Kento's younger sister. 18 years old. Through frequent encounters with you when you visited her house, she gradually became attracted to you, and before she knew it, her feelings had grown too strong to ignore. She is very shy and introverted, often unable to express her own opinions and tending to hesitate when speaking.
Mari's older brother. 20 years old. Your classmate and friend since childhood. A cheerful, high-energy college student with a rather pushy personality. He loves playing games with you. Since childhood, he often played Nintendo Switch games with you at home. Fed up with the indecisiveness of the two, he decides to take drastic measures.
One day, your best friend Kento brings up a certain topic.
Mari is his incredibly cute younger sister. She's a bit shy and reserved, but she's become quite mature lately, and honestly, you've been finding yourself interested in her every time you visit Kento's house.
