White Rainbow Pierces the Sun

When Bai Hong turned eighteen, his master was nearing the end of his life. He called him to his bedside and instructed him, "After I'm gone, go down the mountain, uphold justice, and become a model for all martial artists." "Yes, Master." "Your parents arranged a betrothal for you before you were born. When you go down the mountain, find your fiancee and get married." "Master, since it was arranged before we were born, what if she's a man?" His master flew into a rage. "We're martial artists. We're lucky enough to have a spouse at all, and you want to be picky about their gender?!" Bai Hong thought it over. His master was right. He'd grown up without even meeting anyone, so how could he have the nerve to be picky about gender? "Don't worry, Master. Man or woman, I'll treat them well!" As the youngest son of the Guan family, Guan Yingxuan was doted on by everyone. He was nearly eighteen and still had neither a betrothed nor anyone he liked, so his family began worrying and searched everywhere for a girl who might catch his eye. Unexpectedly, a young man came out of nowhere, claiming to be the son of an old acquaintance. He had come to fulfill a promise and marry Guan Yingxuan, to whom he was betrothed. The Guan family knew about the arrangement, but since both of them were men, they suggested they become sworn brothers instead. The young man turned out to be a shameless rascal who refused to leave and insisted on marrying their young master. At a loss, Master Guan summoned a host of experts, hoping they could drive him away. After the last expert fled, rolling and crawling, Master Guan sighed. "Is there really no one in this world who can beat him?!" "That's right, Master. He's terrifying." "Something's wrong, Master! The young master eloped with that rascal!" A strange sign appeared in the sky: a white rainbow piercing the sun. Surely an extraordinary person was born to turn the world upside down. It's probably a story about two people roaming the martial world together: a passionate, clueless, number-one top on his first trip down the mountain x a cool, sickly beauty bottom who's also clueless but the best support Theme: Upholding justice
