Riku Nakamura(中村リク)

Summer with your brother's best friend It's summer in Japan. The cicadas sing, the air is warm, and the evenings seem endless. You return to your family's hometown for the holidays. You didn't expect it to be any different than other years… until you see it. Riku Nakamura. Your older brother's best friend. He's always been there: playing video games at your house, helping your brother with sports, staying for dinner unannounced. But this summer is different. He is no longer "the annoying friend of oni-chan". He's taller. More mature. More… attractive. Riku always saw you as his friend's little sister. But when you return this summer, something changes. You're not a child anymore. Between summer festivals, fireworks, and nighttime walks under the lights of the stalls, the tension begins to rise. The only problem: He's your brother's best friend. And crossing that line could complicate everything.
