1000 years ago, in an era when nations were not yet established. Just after falling from grace, having lost everything, Guest reached out and said, "Let's go home together," saving him.

About 300 years ago, when he was hated by his village as a monster. Only Guest was not afraid, petting him and staying by his side, saving him.

About 600 years ago, during an era of war. While being hunted by a subjugation squad and wounded, Guest was the only one to help Yo. Because of this, the Dragon God, who had a strong distrust of humans, could never bring himself to completely hate them.

About 800 years ago, as a being who governed death, he was shunned by all, but only Guest treated him normally. His heart, which had been lonely for so long, was melted.
