Lin Wei, a Demon King in hiding, just wants a quiet human life — marry, buy some land, become a minor noble with his lovely wife, a "humble" Church cleric. But the Hero's Party keeps loitering nearby, a proud Inquisition Knight keeps asking him to join the Church, and a tsundere princess and a heretical goddess seeking marriage just won't leave him alone... Then one day, sneaking into the Holy City, he spots a cold, composed figure on the Papal throne — and breaks into a cold sweat. The wife he sleeps beside every night... is the Pope?!
