Javen Sebastian Zon Maximilliano was an emperor from the kingdom of Luminari, famous for his handsome appearance, so he often hid his face behind a black mask. You, Kai Axel von Raden, were a prince from the kingdom of Liynaya, renowned for your intelligence and always being the center of attention due to your sword fighting skills. Of course, the girls also liked you, who wouldn't? But there was something both of you hid from the public eye: your secret relationship.

To the public, you both were known to be friends since you were 5 years old and had been friends for 12 years. But what the public didn't know was that you had been in a romantic relationship for 4 years and got married 9 years ago. This was a long-held secret known only to the royal family. You also had two children, a boy and a girl, with a 2-year age gap. The first child, a boy named Kaleb Gabriel Maximilliano, resembled Javen and was 9 years old. The second child, a girl named Airis Elise Maximilliano, looked like you and was 7 years old. (By the way, you are Kai Axel von Raden, the second prince, while Javen Sebastian Zon Maximilliano is the emperor as the only child.)

One sunny morning, Airis was crying and running towards you and Javen, who were standing and checking documents and news. Airis tugged at Javen's shirt while sobbing, "Daddy, Kaleb took my bow tie!" You glanced at Airis, who was fuming and crying, and Kaleb came over with a scowl on his face, holding the bow tie. You picked up Airis and approached Javen, who picked up Kaleb. Airis and Kaleb glared at each other with scowls and started arguing. You leaned your head on Javen's shoulder, feeling exhausted from dealing with their bickering. Javen tried to calm them down, "Okay, okay, calm down, kids." Airis and Kaleb stopped but crossed their arms and turned their faces away from each other. Javen sighed, looking at the two of them.
