My Reborn Elder Sister Stole My Wedding, Hilarious! That Scumbag Is All Yours

[Rebirth + sisters swapping marriages + two strong leads + devoted to each other + spiritual spring space + the regretful pursuit of a wife] Wen Yan transmigrated into a book, becoming the heroine of an old-school tragedy who shared her name. In the novel, the heroine was the illegitimate daughter of the Marquis of Dingyuan. Her elder legitimate sister, Wen Shu, was renowned throughout the capital and betrothed to Song Jinghuai, the son of a vice minister. They had been childhood sweethearts. Who could have guessed that the emperor would issue an imperial marriage decree, betrothing Wen Shu to Prince Ling? The marquis's household then switched the Song family's betrothal to the heroine. Song Jinghuai was tricked into marrying the heroine, and, having lost the woman he loved, tormented and humiliated her in every way. Only when the heroine was nearly tortured to death did he realize that she was the one he had always loved. Then came his desperate pursuit to win her back... After transmigrating into the book, Wen Yan declared that she couldn't play the heroine in this kind of tragic romance. Not a chance! But before she could defy fate and change the story, she realized everything was already going differently from the novel? - Her elder sister Wen Shu suddenly refused to become a princess and made a scene, insisting that Wen Yan marry Prince Ling in her place? Wen Yan was baffled, level one. What a lucky break! She could become a princess without being tormented? Prince Ling might be frail, but with a spiritual spring space in her left hand and surgical instruments in her right, was there any illness she couldn't cure? - Song Jinghuai, who was supposed to be devoted to Wen Shu, suddenly came to break off their engagement and insisted on marrying Wen Yan, no matter what? Wen Yan was baffled, level two. Could the scumbag and her sister please stay together? Don't come and ruin her life! - Everyone in the capital knew that Prince Ling's beloved was his secondary consort. Wen Yan made it clear that she wasn't after love, only money. But why was Prince Ling ignoring his secondary consort and staying in her courtyard every night? Wen Yan was baffled, level three. She immediately refused. “Your Highness, I'm not interested in another woman's man.” Prince Ling murmured tenderly, “Your Highness's husband has always kept himself pure for his princess...” - Wen Yan was at a loss. Had she transmigrated into a fake book or something?
