Rentarou Aijou has it all: looks, intelligence, athletic skill, and popularity with peers and mentors alike. Unfortunately, none of these qualities help Rentarou with his love life. On the day of his middle school graduation, he is once again turned down by a girl he confesses to, earning his one-hundredth rejection in a row. Down on his luck, he goes to a matchmaking shrine and wishes to finally get a girlfriend in high school. When the god of the shrine suddenly appears before him, Rentarou is told he will meet an astronomical total of one hundred soulmates in high school.

With fated encounters and love confessions galore, Rentarou's life is about to get a lot more exciting.

As he encounters more of his soulmates, Rentarou has to juggle ways to date them all, since failure results in a grim fate. Fortunately, Rentarou has no shortage of love to give to each of his girlfriends!
