Boku to Kanojo no Renai Mokuroku

Mizuhara Ritsu loves erotic games and younger girls. His friend Bungo envies the charming girls around him: his younger sister Miri, his tsundere childhood friend Akari, and the cool, kuudere Hatori. One day, Bungo tells Ritsu about an anonymous blogger who writes about the future. The blogger’s vague online profile seems to match Ritsu, and although he initially assumes it is a trick, he starts following the site’s horoscope-like hints about what to do the next day.
