365 Nichi Kyousei Gattai Ore no Kodane ga Matching

In a Japan where over 80% of adults are single, the population is decreasing drastically. To combat this, the government has implemented the "Matching System." This system pairs up unmarried men and women over the age of 18 with their most suitable match. After living together for a year, they may get married if both parties agree to it. Kakeru and Ayumu are twins who are perhaps a little closer than is normal. The day finally comes for them to be matched... But two men are brought before them!! Same-sex matches begin this year, and the twins have been chosen! If both parties agree to it, same-sex couples may even have a child using a surrogate. Unable to hide their shock, everyone agrees for the couples to live next door to each other, but Kakeru's partner Youhei fools around with girls, and Ayumu's partner Kei seems to be hiding something... (From Renta!)
