Substitute Bride: My Mysterious Loser Husband

“I went to my boyfriend's apartment with a custom cake to surprise him for our third anniversary. Instead, I found him in bed with my wealthy stepsister, Sienna. She smirked in his oversized t-shirt, asking when he would finally dump me. I dumped him on the spot, but my nightmare had just begun. The hospital called, demanding immediate payment for my beloved nanny's life-saving surgery. My adoptive parents coldly refused to help, offering a sick deal instead. They would only pay if I took Sienna's place in an arranged marriage to a notorious "loser" from the powerful Knight family. Sienna was pregnant with my ex's baby and refused to marry him. To save the only mother figure I ever had, I sold my future and agreed to the sham marriage. But on the wedding day at City Hall, my fiancé didn't show up. Sienna brought my ex to witness my humiliation, laughing that even a useless loser didn't want me. "Look at you, so pathetic. You've been stood up." She even posted a photo of me sitting alone to broadcast my misery to the world. I was completely cornered, suffocating under their endless cruelty and the fear of losing my nanny. I fought back with blackmail to make her delete it, but the clock was ticking, and my hope was turning to ash. Just as I thought I had lost everything, the office door swung open, and a breathtakingly magnetic man walked in. "Sorry I'm late. Is Avery Hayes here?"”
