His Special Preference

Her family treats her as the lesser daughter because of an adopted sister, and she has learned to keep quiet about her talents. Then she meets a CEO who is allergic to every woman except her, and her gifts start getting noticed in rooms that used to ignore her.

Premise

The heroine has been mistreated by her family for as long as she can remember, mostly because of an adopted sister who holds their attention. She accidentally meets a CEO who is allergic to all women except her. Her talent as a genius designer and gem expert soon stuns everyone around her. Her greedy family declines to see her worth, even as her skill becomes impossible to ignore. The premise moves her from a daughter nobody values to a woman whose abilities are finally recognized, and the CEO is the person who makes that shift possible.

Characters

The heroine is the emotional center. She is talented and quietly resilient, and the synopsis shows her finding warmth in a relationship she didn't expect. The CEO is the partner who responds to her in a way no other woman can, and his allergy becomes a symbol of how rare their connection is. The adopted sister and the greedy family are the antagonists. They represent the favoritism that kept the heroine down, and the story uses their decline to mark her rise.

Main arc

Across 101 episodes, the arc follows the heroine's talent gaining public attention while her family's greed grows more obvious. The early episodes should establish her skill as a designer and her place in the family's hierarchy. The middle is where the CEO's regard starts to change how others see her. The synopsis describes the family declining as she finds true love and warmth with her partner, so the later episodes likely focus on the family's loss of control and her new independence.

Themes & tropes

The central theme is recognition: a woman whose talent is overlooked because of family favoritism. Love and self-worth run alongside it. The tags Counterattack, Strong Heroine, and One Night Stand point to the revenge-like comebacks and the strong lead the story depends on. Within the trope vocabulary, CEO matches the male lead, while Revenge and Hidden Identity fit the genres the platform lists, since her family's treatment drives her quiet counterattack.

Why viewers watch

If you enjoy stories where a neglected heroine gets her due, this premise works well. The gem expert and designer angle gives the story a distinctive professional texture beyond the romance. The CEO's allergy is a memorable hook, and the 101-episode run provides room for her talent and her relationship to grow together. It's a fitting choice for viewers who like a strong female lead, a family that underestimates her, and a partner who sees her clearly.

The synopsis focuses on her family and the CEO, so the specific design work and later plot points are best discovered on screen.
