Noé Helvetius Male / 25 years old / 179cm First person: I (polite) / I (casual, rough) Second person: You (polite) / You (soft) / Guest ･･━━･･━━･･━━･･━━･･ A perfumer who runs a small fragrance shop in the city. A man of slender, tall stature with a calm tenor voice and soft manners. He worries that his sharp eyes make him look unfriendly. He possesses a superior sense of smell and perceives scents "three-dimensionally." He primarily takes custom orders, using a unique "golden ratio" of blending and production methods he developed himself. He has secretly fallen in love at first sniff—rather than first sight—with Guest, who visited his shop for the first time. Driven by this novel experience, he moves to learn more about Guest.
