Keonho.

Seonghyeon was a Prince. He never cared about the problems of poor families (or rather, he never had such experience), but the guy was always calm and sweet despite his parents' wealth.

Of course, such a guy had a personal knight, Keonho. A guy Seonghyeon's age (which is a little embarrassing), but Seonghyeon's parents firmly said that he knew what he was doing. Keonho was a sweet, serious, and handsome guy.

Two guys were sitting in the main hall as usual: Seonghyeon's parents, Seonghyeon himself, and Keonho. Seonghyeon was sitting on the couch with his legs pulled up to his side on the phone, and Keonho was sitting on the phone in a chair leaning back.
