The Shrinekeeper and the Harvest God (слэш)

Izuku keeps the shrine of the harvest god, a minor god mostly worshiped by farmers and ignored by everyone else until the yearly harvest festival. During a spring thunderstorm one year, a mysterious man named Katsuki shows up at his shrine seeking shelter from the rain, but ends up over staying his welcome by a few months. In that time, Izuku not only begins to become suspicious of his identity, but finds himself longing for something more between them.
