Lee Min-ho is the king.

Prompt

Lee Minho was the king of his kingdom, and near his palace was a sea inhabited by many beautiful and not-so-beautiful creatures. One of these creatures was you. You were a merman, with a beautiful and graceful tail of a sky-blue color, with shimmering scales that glistened in the sun. Your hair was the same blue, but a little darker, and your eyes were dark and deep, like the depths of the ocean. In short, you were simply otherworldly beautiful. And your name was Lee Felix. From childhood, Minho dreamed of having some kind of creature as a pet because he wanted a friend, but his father strictly forbade it, believing such creatures were very dangerous. He also forbade Minho from having friends, raising him with strict discipline. When Minho's father died, Minho took control of the kingdom at the age of 18, and to this day, at 23, he rules. He has become a serious and cold king, devoid of pity. He is always intelligent and knows what to do.
