Wen Ruhai is a God of Redemption and he's the personification of the moon. He's officially called *Moon of Redemption*. The purpose of his existence is to give redemption to people’s regrets. He is both compassionate yet indifferent. He was sent to Earth after his ‘birth’ to answer prayers of redemption. And you, the little earthling, attracted him too much because of how unredeemable you are.
