You Don't Think I'm the Stand-In, Do You?

Wen Xu knew she was a stand-in. They were in love with her older sister. For her sister's sake, Wen Xu willingly had dinner with a reckless lunatic, went on an island vacation with a sinister CEO, and stayed up all night gaming with a green-tea heartthrob from school. She did it willingly and never crossed the line. She was the perfect stand-in. When her sister returned home after a breakup, her suitors went back to her side. They still adored their beloved first love. The only person they owed anything to was Wen Xu, the younger sister they'd callously abandoned. So when Wen Xu took the initiative to leave, the playboy decided to turn back and return her feelings. Wen Xu walked away with her suitcase, resolute. Leaning against the doorframe, the playboy made no move to stop her. He scoffed indifferently. "Don't come crying when you regret this." He knew Wen Xu was hopelessly in love with him. She'd willingly become her sister's stand-in just to be with him, loving him so desperately she'd lost her dignity. Wen Xu couldn't live without him. Sooner or later, she'd come back. The CEO and the school heartthrob thought so too. Six months later, someone photographed Wen Xu in a red dress, sitting alone on the roof of a skyscraper, apparently about to take her own life. The playboy's heart skipped a beat. In the end, he couldn't hold back. He hurriedly started his car and raced to see her. But when he arrived, he found that besides his two equally frantic, detestable rivals, there was another man there to find her. The man was pale and frail, yet breathtakingly beautiful, like a gentle breeze blowing across an icy snowfield. He was utterly untouchable. He held out his palm to Wen Xu. "Come down." Wen Xu stared at the man's face, her eyes reddening. Disbelief and guilt mingled in her voice. "Honey, you're not dead?" Seeing this, her rivals stiffened as if struck by a hammer. And the most infuriating part was... The more they looked at that man's face, the more damn familiar it seemed. They'd treated Wen Xu as a stand-in, but in the end, were they the ones who'd been the stand-ins? [Note]: 1. One-on-one romance, happy ending, both leads are each other's first. The male lead is an aloof, untouchable beauty, the beloved first love of everyone. 2. None of the characters are perfect. A reverse stand-in romance, all the male rivals get their comeuppance, and plenty of romantic drama. 3. The original female lead will be portrayed negatively! I'm tired of writing gorgeous, domineering older women who use their beauty to get their way. This time I want to write an innocent younger sister, though she still fits my personal preferences. The female lead's beauty is off the charts. For specific content warnings, see the author's note in Chapter 1. Theme: Love yourself first, and the world will love you too.
