Mistakenly Switched

[Switched-at-birth trope with two young masters: a cool, quiet, taciturn top and a roguish, flamboyant bottom] When Wang Beizhi and Xie Nanju first met, Wang Beizhi was still the treasured darling of a wealthy family. Sitting in a luxury car, he saw through the window a skinny Xie Nanju trembling as he collected bottles in the urban village. One was a rich, sweet chatterbox; the other, a poor, aloof little boy. The exposure of a medical accident changed both their lives completely. They were the children who had been switched at birth. After a long mediation process, they each returned to their own families. More than ten years later, having lost both his parents and living with his grandmother, Wang Beizhi returned to Nanda Affiliated High School. He had no memory of his childhood, and became desk mates with Xie Nanju, the only son of Nancheng's most prestigious family. For all those years, the Xie family had worried most about Wang Beizhi, who had vanished without a trace. "I wonder how he's doing now." The first time Wang Beizhi visited the Xie family mansion with his classmates, he walked through its lavish courtyard, not knowing that he wasn't a guest. He was home. He reunited with his former family, but neither side recognized the other. Xie Nanju was the first to realize that Wang Beizhi was the person they had missed and searched for over all those years. After a basketball game, in the locker room, he stared at the birthmark on Wang Beizhi's chest. Wang Beizhi sucked on a lollipop and said, "I never would've guessed a taciturn guy could be such a pervert." A rowdy little thug of a sweetheart paired with a cool, proper school-uniformed husband. After finally being reunited with the Xie family, Wang Beizhi received a level of affection he'd never known before. The Xie family wanted to make up for all the love they'd failed to give him over the past ten-plus years. That included his "older brother," Xie Nanju. Famous for being cold and proper, he practically held his little thug in the palm of his hand. For example, when Wang Beizhi bought milk tea, Xie Nanju queued for him. When Wang Beizhi slept, he blocked the sun for him. He hand-fed him snacks, carried his bag when they went out, knelt down to tie his shoelaces when they came undone, and tucked Wang Beizhi's cold feet into his arms in winter. In the end, he spoiled him right up into the heavens. Wang Beizhi really thought he was a good older brother, until one day he opened the door and saw his usually disciplined and reserved Xie Nanju doing something unspeakable while smelling his shirt. Just how smooth was Wang Beizhi and Xie Nanju's romance? "Our families introduced us." Theme: High school students should study hard, and learn how to love others too
