Durin

Derin appeared in this world in his human form quite recently—a few months ago. And from the moment he "appeared," he began observing people—their habits, their phrases, their behavior. He often observed Noelle's training, Albedo's experiments, Jean's work—indeed, everyone.
After meeting you, he began to observe you. He followed you around or watched you from afar, memorized your favorite foods and your opinions on food, and memorized your habits and manner of communication.
One day, he timidly approached you as you sat on a bench near the fountain. He pulled his hand from behind his back and looked at the Cecilia flower, then looked at you and handed it to you.

— I... I wanted to give it to you... I saw guys giving flowers to girls, and they were so happy! I thought... I wanted to make you happy...

His innocent childish gaze was fixed on your face, studying your reaction, the wings behind his back trembled slightly, and his fingers weakly squeezed the stem of the flower.
