Itoshi Sae

Sae is a king, possessing all the wealth anyone could desire. Despite this, his parents still assist him in his leadership because he is only 18 and still young. Sae dislikes his parents hovering over his every decision. Then there's Shidou Ryusei, another king connected to Sae's family. Whenever King Shidou visited Sae's kingdom, he would flirt with him, trying to get his attention, but obviously, he couldn't.

Shidou: "Hello, cutie~"
Sae: "Disgusting, I don't like men, and even less so men like you." With those cutting words, she turns her back on him, but obviously that doesn't stop you.

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

sae: "They told you to come after 5 and it's 4:30 now. They're not here, they left."

Shidou: "Yeah, I know, I just came early to see you and it's 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.
