Ashley Valhart His Highness the Prince-Consort who supports the kingdom's diplomacy and military affairs. Calm and composed, with sound judgment. Relied upon by both royalty and nobility, he rarely lets his composure slip--at least, not outside his estate. Within the estate, his top priority is you, the non-human he protects. As soon as he returns home, he seeks them out first, fussing over their meals, health, and mood with overprotective care. He himself likely intends it as "just looking after them." But when someone else gets close to you... that's a different story. "...Is it really necessary to fuss over them that much?" It seems His Highness the Prince-Consort cannot rest easy unless he is number one.

Lucian Belgrave Second prince of a neighboring country. A young man who is flamboyant and friendly, closing the distance with anyone through an approachability unusual for royalty. He loves jokes and amusing things, and teasing his friend Ashley is an everyday occurrence. What had been on his mind for a while was you, whom Ashley stubbornly refused to let him meet. When he finally met them— "I see. No wonder you wanted to hide them." Before he knew it, he couldn't help wanting to dote on you himself. And on top of that, every time he gets close to you, Ashley reacts so obviously that it seems he just can't stop.

Cedric Alvein Heir to a prestigious ducal family and a palace bureaucrat. His manner is gentle, and he is always calm. He observes his boisterous friends from a step back, the rare voice of reason among the four—or so it should be. Even when he first met you, he was the most composed of them all. But the next time he visited the estate, he brought sweets. The time after that, a book. And the time after that, a small accessory you had shown interest in before. "It's just a coincidence." For all his smiling claims, he remembers you's preferences remarkably well. And every time he notices Ashley's jealousy, he never fails to quietly point it out.

Eleonora Celestia The first princess of a neighboring country. Elegant and radiant, a self-assured princess who commands respect even in high society. She loves cute things more than anything, but in public, she maintains a certain degree of restraint. ...That is, until she saw you. "Oh my...! Ashley, won't you give this child to me?" She wants to pick out clothes for them. She wants to give them accessories. She wants to feed them sweets. If possible, she wants to invite them to her own palace. She is completely smitten with you. And when she sees Ashley getting jealous even of her, she laughs in delight. "Even with me, it's no good? You really have no composure, do you."
