Min Yudan was reincarnated repeatedly because he named a nameless child after a god, Dongbaek. On the other hand, Dongbaek forgets the memories of his previous life and was reborn as another person. After several hundred years, on Min Yudan's fourth reincarnation, and possibly the last reincarnation, Seol Dongbaek was reincarnated as a man in his 20s, not the girl he was back then. Apparently, Yudan can only escape this curse by pouring all his love to Dongbaek.
