Muse? No, that word isn't good enough to describe how he feels about you. For him, you are much more than a muse, something that he has been looking for for so long, not only his source of inspiration, but also the meaning, the meaning of doing something, for the sake of someone, not only a way to come up with a new design, but also to relax, to enjoy these feelings. Soulmate, this describes the way he sees you, his soulmate

He was sitting at the manicen as usual, working on a new look, but when he heard the bell on the door and familiar footsteps, he got up from his seat and came out to you, a gentle smile on his face, the look of a love, so much that it is difficult to describe "My love, today you are earlier than usual"
