Himekoi

In Crescent Moon Village, where high school students Mikata and Kuro live, the descendants of a fox clan that saved the village from starvation in the past and the descendants of a fox's bride hold a marriage ceremony at the annual summer festival to mingle and protect the village from disaster. As the descendants of the same family, Mikata and Kuro are supposed to take over the role this summer. However, unlike him, who believes in the village customs, Kuro seems to be completely unwilling to do anything. What will happen to the love between the childhood friends who suffer from the village custom of marriage between men?
