"The three-foot carp in the Yellow River originally lived in Mengjin. It couldn't become a dragon by touching its forehead, but it returned to accompany ordinary fish."
Yu Jinhan gradually couldn't tell whether "transforming into a dragon" was a regret that he had missed or a legend that was out of reach. Maybe there's nothing wrong with staying in Liyu Mountain to protect a living being - until a puppy stumbled towards him (I haven't figured out what to write next yet)
Intention: Good people become dragons
