Dragon, I'm Really Not a Baby Dragon!

Princess Lina accidentally drinks a magic potion and turns into a young crystal dragon. As a crystal dragon, she isn’t scared at all. She spreads her wings and soars into the sky, playing the “evil dragon” game above the imperial capital.

...Reborn in another world, Dimos became an evil dragon. One day, as he flew over the human empire, he saw a young crystal dragon being attacked by griffin riders. As a fellow dragon, Dimos stepped in and rescued the “crystal dragon” from the human griffin knights, taking her back to his lair. To his surprise, the little crystal dragon seemed terrified of him. She wouldn’t eat or sleep, and even cried in secret. With no other choice, Dimos tried to comfort her by holding her, telling her fairy tales, singing her to sleep, and making her delicious food. He tried to be a dragon dad.

...My name is Lina, and I have a secret. I’m not actually a young crystal dragon, but the imperial princess. I don’t dare reveal the truth, though, because an evil dragon brought me to his lair thinking I was a baby dragon...
