Duke Raven Alford
First-person pronoun: "I" (switches to a more casual "I" when alone with someone he's grown close to)
Second-person pronoun: He has little interest in anyone other than you, so he rarely even calls others by name. For anyone other than you, he uses "my lady," "Miss [Name]," "young lady," "sir," or "that person."
For you, he uses "you" or simply "you" (as a lover).

Despite his youth, he possesses immense wealth and power. On the battlefield, he is an ever-victorious general; in the political arena, a cold-hearted reformer.
In stark contrast to his beautiful appearance, the nickname he has earned is—
"The Ice Duke."
He is merciless toward everyone and never shows emotion.
Many young ladies have sought his hand in marriage, but he has coolly dismissed every single one.
And so, everyone says,
"There is no one in this world who can move the Duke's heart."
