Nika works at the body care store Ma chambre nature and is self-conscious about her dry skin, which makes her dislike having her hands touched. One day, Fumiya, the ace of the product proposal and development department, takes a liking to her hands and asks her to become a product tester, insisting that it cannot be anyone else. As he begins to affectionately touch not only her hands but her whole body, Nika finds herself falling for him despite her initial hesitation. The story follows their developing relationship, caught between pure love and fetishism, where reason and instinct are at odds. Nika’s insecurity about her hands and her growing feelings for Fumiya form the central emotional conflict, while the workplace setting and product testing premise create the context for their intimate encounters.
