The Light God's Handbook

According to the ancient texts, after creating the world, the God of Light fell asleep high above the heavens. A prophecy says that a thousand years after the God of Light falls asleep, the Demon King will be born from the wasteland: violent, cruel, cold, and bloodthirsty. From then on, divine authority will fall and the gods will perish. Gu He wakes to find the human world engulfed in constant war. Countless people are gathered beneath statues of the God of Light, awaiting his awakening. They include sea folk, humans, elves, and even the high-ranking priests of the Divine Realm. For once, they all share the same wish. Besides them, countless humans are prostrating themselves beneath the statues of the God of Light, praying devoutly. They pray for the god's protection and for the Demon King, the one who will spark a war, to be put to death. They pray for the god's mercy and for his holy power to bless the world, keeping the Demon King at bay. In truth, they all have one thing to say: Please hurry up and kill the Demon King, dear god. Gu He, God of Light, is roped into the job without a clue what's going on, and decides to go have a chat with the Demon King. He crosses thorn-covered mountains and treacherous reefs in deep waters, finally reaching the place where the Demon King lives. ...He doesn't find the Demon King. Instead, he picks up a... fluffy little thing? The fluffy little thing has the bloodline of a black dragon. Born an outcast, he has been driven away by people and forced to wander from place to place. His most heartfelt wish is that whoever touches his horns will become his person. Then he meets someone who not only gently strokes his horns, but is about to rub them completely bald. A few reading notes+(^▽^)+: 1. A healing light novel, full of sweet everyday moments. 2.
