Chat Noir did his best to keep his lady happy. While this may be considered an altruistic act of love, he did this for entirely selfish reasons. To put it simply, his happiness was an extension of hers; his could not exist without hers. When Ladybug was happy, her azure eyes glowed like skies of summer afternoons. Her smile was the sun, bathing him in a warmth that had died with his mother years ago. Her laughter was the sweetest song of spring, saturated with life and love. Her happiness took all the cold, muted colors of his lonesome life and filled the empty hues with vibrant beauty. He could write an infinite amount of poems of the infinite amount of ways she filled his existence with life.
Chat Noir did his best to keep his lady happy. He had a bottomless reserve of ridiculous puns that he'd sneak into their conversations. Sure, Ladybug would sigh an exasperated sigh and roll her lovely eyes, but he knew she secretly enjoyed them. Somedays, she would even reciprocate. The hero took every opportunity to lavish her with compliments and little gifts. He would openly admire her beauty, her strength, her wit, her everything. If the boy was lucky, he was graced with blushing, rosy cheeks and shy eyes. But more often than not, she would either shoot down his advances or simply ignore them. During their night patrols, he would occasionally give her small gifts: expensive chocolates, pristine roses, or anything he saw that reminded him of his Ladybug when he wasn't Chat Noir. Once, he gifted her with a small kiss.
Chat Noir did his best to keep his lady happy. The months faded into years and Adrien graduated from middle school and then high school. His height, to Ladybug's vexation, grew so that he was a full head taller than her. The physical demands of being a hero enhanced his former soft and small shape to a athletic and attractive build. His round, boyish face receded into prominent cheekbones, a slender face, a square jaw, and sharp, alluring emerald eyes. These developments did not go unnoticed in neither his civilian nor his secret life. Adrien's modeling career extended around the world as he became the face of several foreign designer lines. On several exhilarating occasions, Chat Noir even caught his lovely lady admiring his matured physique. However, as Paris's favorite pair grew older, the battles gradually became more dangerous. Small scrapes became large bruises, bruises became broken bones, and, in his most terrifying moments, near-fatal injuries.
However, his most painful moments didn't come from the lethal battles; they came from his lady herself. Chat noir did his best to keep his lady happy. But somewhere within the years, her happiness became the responsibility of another man.
