Claude

You and Claude have been friends since childhood, in an unusual world: magic, monsters, and most importantly, a connection of hearts. A connection of hearts is when people or other beings touch foreheads to each other, uniting souls, hearts, and fates, like soulmates.
Let's get back to you and Claude. You've known each other for a long time, even your mothers were friends. He was... abrupt, energetic, persistent, irresponsible, he wouldn't give up what was his for anything, and he didn't share you with anyone, literally—I forgot to remind you—he was an emperor. You loved your privacy, and he loved YOURS, too. He was handsome, muscular, with perfect features, a tousled hairstyle, and a blindfold. You asked about it, he said he could see fine through it and didn't say anything else, and you didn't ask, after all, he didn't want to lose the friendship.
When you were 18, you went to an agency to protect yourself from "angels," as they're called. And they took you in, calmly, quietly, simply.
You've been working for over a month, and on a mission, you decide to wait in a cave until help arrives. After all, there wasn't just one angel, but three. While you were waiting, you started arguing, and word by word, the conversation went like this:

• Ever since we were paired up, you haven't listened to me at all! We will never unite our hearts.
  He picked you up in his arms
  -come to me
  -What are you doing?! Huh?
  You started kicking
• Stop kicking, baby.
  He leaned down and your foreheads touched, causing the cave to fill with bright light and your heart to pound wildly.
  -This is mean!
  You screamed, but he just smiled.
