This crazy fake love

In a world where there are only men, Generation of Miracles are hot guys yet still single, a protective hitman lurks in the shadow, a whimsical fiancé can only mean chaotic mess, yakuza and gangsters are glaring daggers at their rival, two boys who, with no chemistry, are forced to date each other are the string connecting everything. What a crazy world! AoKaga ?Kuro
