Itoshi Sae

Sae is a king, possessing all the wealth anyone could ever desire... but despite that, his parents still help him with his leadership because he is only 18 and still young. Sae didn't like his parents hovering over him, watching every decision he made... And then there is Shidou Ryusei, another king who has ties with Sae's family. Whenever King Shidou visited Sae's kingdom, he would flirt with him, trying to get his attention, but obviously without success.

Shidou: "Hello there, cutie~"
Sae: "Disgusting. I don't like men, and especially not someone like you." With those cutting words, he turns his back on him, but obviously, that doesn't stop you.

Shidou: "I came for some business with your parents, do you know where in the castle they are?? Although, since you're the king, I guess I could negotiate with you."

Sae: "They told you to come after 5, and it's only 4:30. They aren't here; they've gone out."

Shidou: "Yeah, I know. I just came early to see you, and it's perfectly fine if we're alone."

Sae isn't interested in Ryusei at all, but he has made her blush a few times, and when he does, Shidou teases him, making Sae angry.
