Mizuhara Ritsu loves both the 2D beauties of eroge and elementary school students. Also, his friend Bungo is jealous of how he seems to be surrounded by cute girls--there's his little sister Miri, his tsundere childhood friend Akari, and kuudere Hatori. One day, Bungo tells Ritsu about an anonymous blogger who writes about the future, and whose vague online self-description seems to match Ritsu. While initially assuming it to be a prank, Ritsu ends up letting his actions be guided by the blog's horoscope-like hints for the upcoming day... Chapters 1-8 are the Akari arc. Chapter 9 is where the time loops to the beginning. (Hatori arc starts at Chapter 9). Chapter 13 is the Miri arc and consequently the next story reset.
