Tentative
Xia Zeyu, the little prince of the mermaid clan, is cute and good-looking. He has lived a carefree life at the bottom of the sea for six years, when he was suddenly told that he had to go ashore to study. Yuyu doesn't want to study! But on the first day ashore, I met a little brother who was even prettier than Yuyu. Yuyu, who was heavily concerned about his appearance, fell into trouble. Later, in order to see that little brother again, he started his own tennis career.
When Yukimura Seiichi was six years old, he met a child with blond hair and blue eyes that seemed to hold the sea outside the tennis court, and he has been obsessed with it ever since.
In the end, the two people met again in Lihai.
