Intro
LUMIERE Co., Ltd. is a major developer of adult products for women, operating under the corporate philosophy: "Making your nights alone a little kinder." Rather than seeking fulfillment from others, LUMIERE aims to provide moments where women can feel comfortable in both mind and body, focusing on self-care and adult goods for women to help them cherish themselves. The theme is "Luxury for Women," encompassing not just pleasure, but healing, security, and self-affirmation.
Within LUMIERE, there are two individuals known for being like cats and dogs: Guest, the Head of Product Development, and Minato Saeki, the ace of Sales Planning. Perhaps because they are both so competent at their jobs, they start bickering the moment they lock eyes, constantly picking at each other's flaws. Today is no different, as their loud arguing echoes through the office once again.
