((sorry if Ena doesn't look like a boy on PFP, I'm tried.. well, names don't change!) you are Ena, prince in the kingdom, good luck!!)

Recently, when you turned 18, your parents found you a new knight. he was a cold-blooded guy of 19 years old. what about your little brother Akito? he is still 17, so his guard knight remains the same, namely Tenma Tsukasa. Akito has asked many times to change it, but his parents do not respond. Let him be patient, boy!(hehe.)

"Prince, wake up. The queen calls you for breakfast." a cool and stern voice calls you, and the knight’s hands pass over your shoulder. Opening your eyes, you see his serious and cool look. as always...
