"Not Her Type"
Vegeta knew he wasn't a conventional match for anyone in the dating department. As far as looks were concerned, he excelled in that. He was handsome, and he also had his strength and intelligence on his side. Oh, did he mention that he was the Prince of All Saiyans? Nothing screamed attractive like being royalty.
Loathe as he was to acknowledge any flaw against his perceived perfection and greatness, he'd be dumb to disregard his bad side. Temperamental, haughty, selfish, ruthless. Those were just a few of the words rightly associated with him. So, yeah, he wasn't what any sane person looked for in a relationship.
And yet, that human woman didn't let those things deter her from pursuing him. The earth princess Chi-Chi, who did, he admitted to himself, met his criteria in a mate. She was strong and could fight, not to mention she was an excellent cook. Seriously, her food tasted like it was crafted by the angels in Heaven, it was that fucking good. And she was definitely easy on the eyes, despite her sometimes prickly demeanor.
Long, inky black hair that fell down her back in rivers, equally dark eyes that glowed with a warmth that melted the ice surrounding his damaged, fragile heart, and lips that were soft as a cloud and tasted sweeter than cotton candy. They were opposites, so it seemed to those around them. Kakarot's friends thought he stole her from him, which did nothing but stroke his ego that he had something that buffoon never could hope to own; after all, his mate was perfection incarnated.
That blue haired woman had some decent traits about her, but her bubbly personality was too obnoxious for him tolerate on a daily basis to such a degree, and they definitely rubbed each other the wrong way more often than not, sometimes to the point where intervention was necessarily to ease frazzled nerves. He definitely lacked patience when it came to her. What Kakarot saw in her, he'd never know, but the same logic could be applied to him and Chi-Chi.
They clashed in a different way, but never failed to smooth out each other's wrinkles. Chi-Chi was optimistic, but realistic. She was familiar with war and death and bloodshed and loss. She knew how heavy the burden of the crown on her head felt like, how overwhelming and challenging it was to be leader to a group of people who depended on you. She had a temper that rivaled his own and wasn't afraid to challenge him not only physically, but mentally and emotionally as well.
She was patient and kind towards him, but never turned a blind eye to the many atrocities he had committed throughout his life, some forced and some enjoyed, but of them he regretted. She held his bloodstained hands in hers and kissed every bruise and ach and scar he had lovingly, selflessly. How could he not be attracted to a woman like her?
Let them judge their relationship and talk all the shit they like. Vegeta never gave a rat's ass about how anyone felt about him, and he couldn't give less of a damn about their gossiping bullshit if he tried. All that mattered to him was the mate he had chosen and the child they created together slowly growing and blossoming within her womb. He was just her type, and she was his as well.
