Takuma Hirose is a young, male high school student, who is blind for unknown reasons. After his mother died an unexpected death, it left a deep emotional scar on him, which caused him to become very lonely and reserved. Due to this, Takuma and his father move from the city out into a rural area and Takuma is enrolled into a new high school. At his new school, he meets several new girls, three of whom he gets to know the most out of anyone else. They are, the firm and obstinate Hayami Kohinata, the kind and obliging Hinata Kagura, and the cheerful and mysterious Otoha. As Takuma interacts with these girls, his medical condition gradually begins to heal.

Noya Itsuki just started his school year at the Ebisugawa High School and since he has always had a fascination with space, he decides to join the astronomy club. However, he mistakenly walks into the all girls Otaku Club. He notices that the members are really weird, but Itsuki has yet to realize that he isn’t in the astronomy club. His life is about to get complicated by being surrounded by so many girls.

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.
