The 100 Girlfriends Who Really, Really, Really, Really, Really Love You

Aijo Rentaro has faced 100 rejections in life, and when he goes to a matchmaking shrine to pray for love, he finds that he will get more than he ever bargained for in high school.

Hakari and Karane learn that Rentaro hasn't had his first kiss yet; they may both be his girlfriends, but they still want his first kiss for themselves.

Rentaro has encountered his third soulmate: the shy and smol Yoshimoto Shizuka.

Rentaro has a plan to break the ice between Hakari, Karane and Shizuka; it involves laughter and Old Maid; but things take a turn for the unexpected.

Rentaro encounters the smartest student in school, Eiai Nano, and it turns out she's a soulmate, too; her extreme rationality leads him to question whether they really are meant for each other.

Rentaro and the girls hit the newly opened water park at Hakari's suggestion, but Karane appears to have come down with a mysterious chill.
