Kimi no Koto ga Daidaidaidaidaisuki na 100-nin no Kanojo

Rentarou Aijou seems to possess every quality that should make romance easy, yet he finishes middle school after one hundred confessions and one hundred rejections. When he visits a matchmaking shrine and prays to finally find love, the God of Love appears and explains that a divine mistake has given him one hundred soulmates in high school.

On his first day he actually meets Hakari and Karane, and both instantly fall for him. The problem is that these bonds cannot simply be ignored: according to the god, a soulmate whose love is not returned will die. Rentarou refuses to choose one girl at another's expense and adopts the only solution extreme enough for the situation: he will sincerely love all one hundred girlfriends. As more soulmates appear, his challenge becomes maintaining the largest possible relationship without letting anyone feel less loved than the rest.
