Synopsis
Rentarō Aijō has confessed to (and been rejected by) 100 girls in his lifetime. On the last day of middle school, he visits a shrine and prays that he get a girlfriend during his time at high school. Suddenly, the God of Love appears and tells Rentarō that the reason for his non-existent love life is because everyone is only supposed to have one soulmate in their life. Due to an error on the God of Love's part, Rentarō is destined to have 100 which is to begin when he enters high school.

Sure enough, on the first day of high school, Rentarō meets the wealthy Hakari Hanazono and Karane Inda. Both girls instantly fall in love with him. Rentarō is also in love with both of them but cannot decide between them. That evening, he revisits the God of Love and is informed that if he does not return the feelings of one of his soulmates, they will die in an accident. Not wanting such a fate to befall Hakari and Karane, Rentarō decides to date both of them simultaneously, with their blessing.

As the story continues, more girls are introduced and become Rentarō's girlfriends, establishing a polyamorous relationship called the "Rentarō Family". The story revolves around Rentarō meeting new girlfriends and the interactions between the Rentarō Family members.
