After I Became a Delicate Young Husband, the Crown Prince Was Hooked

[Please add my upcoming story, The Wealthy Tycoon's Tender Care for His Sickly Beauty, to your reading list] Blurb: Chu Tang transmigrated. He'd heard that the young master of the Cheng family was a sickly man, and he happened to transmigrate into the little husband brought in to bring the young master good luck. On their wedding night, Chu Tang looked at the healthy, handsome man before him... So much for bringing him good luck! Just as he was about to lie down, Young Master Cheng coldly said, "Sleep in the side room." Making someone sleep in the side room on their wedding night? What a jerk! Chu Tang pursed his lips, looking aggrieved as he grabbed his pillow and stormed out. He couldn't count on his husband's family, but luckily he had a knack for cooking. He could set up a little food stall and support himself without having to depend on anyone. On the first day of their marriage, Chu Tang made some lotus root sandwiches to try. Young Master Cheng, coldly: "Take those away." Chu Tang immediately offered them to the dog beside him. "I made these for Dahuang. Young Master Cheng, you misunderstood." Later, Chu Tang excitedly tried to discuss a divorce with Young Master Cheng, only to be turned away. He had no choice but to pack his things, leave a letter of divorce, and run. In the courtyard, he was just about to climb over the wall when he ran into Dahuang. Man and dog stared at each other. Chu Tang waved a hand. "Fine. I'll take the dog and run." He hadn't enjoyed his carefree days for long before he was cornered. His husband, who'd lost his wife and almost lost his dog, tore up the letter of divorce right in front of him. Chu Tang had a delicate constitution and expensive tastes. Even a light pinch made his wrist flush an alarming red. Cold fingertips, dangerously gentle, lifted his black hair. Then a hoarse voice spoke: It sounded like a plea, or an enchantment: "Don't go." Then he found out that Young Master Cheng was actually the crown prince! Oh well, so he's the crown prince. Being a crown princess would be fine too. Once he ascends the throne, Chu Tang will get promoted to empress... Wait, emperor?!
