Can an Ordinary Passerby Top Become Everyone's Favorite?

[Male-Lead-Focused] You are just an ordinary passerby. In a school story, you’re the one who chimes in among the background characters. In a modern urban story, you’re the CEO’s driver. In an ancient setting, you’re a prince’s hidden guard. In a medieval story, you’re the butler. Everything about you is as ordinary as can be. Born with an inability to feel emotions, you’re perfectly suited to these emotionless roles. So you don’t understand... Why you, in the school story, would be cornered in a restroom, trapped in the protagonist’s arms as he kisses you. Why you, in the modern urban story, would be shut inside a car, pushed against the window by the protagonist as he peppers you with gentle kisses, leaving you nowhere to retreat. Why, in the ancient story, when you fail a mission, your punishment is for the protagonist to lift your hem, expose the pale bend of your leg, and leave marks on it with his hand. Why, in the medieval story, after you make a mistake, the protagonist tells you to take off your white gloves, then licks your hand until it turns red. You only look confused when the protagonist is consumed by unrequited love and on the verge of madness. Because you’re just an ordinary passerby with no feelings. [Note from January 15, 2024. One-on-one, true love. Another idea, though I really might not start writing this one. I have too many ideas...] Theme: The soul matters more than appearance, and everyone deserves to be loved
