Qi Xia, a girl from the marine department, picked up a small fish at the beach. That night, the small fish turned into a cold and handsome man, calling himself the Ninth Prince of the East China Sea. He doesn't understand cell phones and can't ride in a car, but he confidently stays at her house. Qi Xia thought she was in trouble, but she didn't know that this dragon had come across three thousand years just to see her again.
