Marrying my friend ex-Husband

"Will you marry me?" Axton suddenly said, causing Emily to hold her breath for a few seconds before widening her eyes.
"What? Marry you?" Emily asked to confirm, making Axton nod. However, Emily burst into laughter, even though it felt awkward.
"You're joking, right? This must be impossible. How could you ask me to marry you? I thought this was just a sign that you're frustrated and making impulsive decisions like this," Emily said, making Axton shake his head.
"Do I look like I'm joking with such a serious face like this? Besides, it's not April Fools' Day. There's no reason for me to lie to you," Axton said, making Emily immediately stand up from her seat.
"No, no, no. I think you've come to the wrong person. How could you come to your ex-wife's best friend to propose marriage? You don't want to ruin our friendship, do you?" Emily asked, making Axton sigh deeply.
"Because you're the only one who can understand, and by marrying you, Grace will realize her mistake," Axton said, leaving Emily speechless.
Emily didn't know whether Grace and Axton were aware of her feelings or not. What she was sure of was that, over the years, she had successfully hidden her feelings well, keeping her admiration and love for Axton, her best friend's husband, to herself.
Emily didn't know when those feelings had emerged. She also didn't know why those emotions suddenly filled her heart, unstoppable and undeniable. Now, Axton had proposed to her for a clichéd reason, to make Grace divorce Ethan, and Emily had reluctantly accepted. Despite facing Grace's anger for being perceived as a traitor, Emily went along with the decision. But Emily knew that this wouldn't be smooth sailing, as she had finally set some conditions for Axton.
"All right, I accept your proposal, but with a few conditions," Emily's decision marked the beginning of their love story.
