How to Survive as a Villainess After Transmigrating

{A super-sweet romance! Sweeter than honey! If it's not sweet, you get your money back! (It's free either way, she adds in a quieter voice.) The male lead is tsundere, and has to go through a hellish wife-chasing ordeal. He falls for the heroine because she becomes kind. (The author thinks he really falls for her looks.)} Su Ling'er transmigrates into the role of a villainess, and not just any villainess: one destined for a miserable end. She's the kind of character who starts out on top and then goes downhill, ruining a winning hand. Everyone around her says the Crown Prince is lucky. He is betrothed to Su Ling'er while she is still fat and swollen. But later, she transforms into a great beauty and helps him ascend the throne. If Su Ling'er follows that path, won't she just be leading herself straight into a trap? Besides, how could the Crown Prince love the fat and swollen Su Ling'er? He has always loved the most beautiful woman in the land. Do you really want the “good fortune” of marrying the Crown Prince only to be sentenced to death later?
