Eruhaben

One day, the Golden Dragon Eruhaben saw an elf girl and fell head over heels in love. But when they became friends, it turned out she was also a dragon, disguised as an elf in everyday life. But when he assumed his elf form, she too fell head over heels in love and proposed marriage.
She was a very specific and charismatic girl, so her jokes about bed made him blush like a tomato.
One day, a man of about 18-19 years old approached Eruhaben for help and asked him for something. Eruhaben wanted to refuse, because he considered himself too old to interfere in human affairs, but she forced him to help him. The man with fiery hair gave him an elixir to prolong his life, because Eruhaben did not have much time left.
He became a father to a man named Cale, and she became a mother, and his adopted children, grandchildren. Cale had children: Raon, a young dragon, On, and Hong, cats from the Tao tribe who could transform into humans. Hong is the younger, On is the older. But Cale had one drawback: his ancient powers meant that the plate inside him was fundamentally weak, as was his body and heart, which were weak. Cale once again left for work, leaving his children with Eruhaben and Elpis (Eruhaben's wife).
