You’ll Regret Stealing Him from Me — My Sister Who Took My Fiancé and Celebrated Was a Fool - Chapter 5

It became clear that Seraphina was a despicable woman.

To be honest, I never liked her much from the start. She was brilliant but impossible to relax around. Highly regarded in social circles, too. Being engaged to someone like that was suffocating. The thought of marrying her and spending my life with Seraphina was something I could hardly imagine. Just thinking about it made my chest tighten.

In contrast, her younger sister Isabella was entirely different. Unlike her sister, she was sweet and sincere. Compared to Seraphina’s perfectionist demeanor, Isabella seemed far more pleasant to be around. More than once, I caught myself thinking though I never voiced it that I wished Isabella had been my fiancée instead.

Ironically, it was Seraphina who brought Isabella and me closer.

“Lord Roderick, might I have a moment of your time? There’s something I must discuss with you about my sister.”

One afternoon, Isabella approached me, asking to speak alone. Her expression was grave, as if she carried some terrible secret. We secluded ourselves in a gazebo in the eastern garden, away from prying eyes.

What she told me left me stunned.

“The truth is my sister has been stealing credit for my work.”

“What?”

I couldn’t help raising my voice. I needed to hear more what exactly did she mean?

“She would ask for my advice about parties, and when I shared my ideas, she would take them without permission. Afterward, she never acknowledged me as the true originator, passing them off as her own. She’s praised so highly in society but that recognition should have been mine.”

Isabella spoke with tears in her eyes, her expression so pained it had to be genuine. It didn’t seem like a lie, no one could fake that kind of anguish.

And if it was true, it was unforgivable. For a sister to steal from her own sibling?

But then again, knowing Seraphina, it wasn’t impossible. If she had been using underhanded tactics behind the scenes, it wouldn’t surprise me. Listening to Isabella, I felt it in my gut. This could very well be real.

“But I have no way to prove it. My sister is so respected in society that if I spoke up, I might be called a liar. Worse, I could end up being painted as the villain. That’s why I could only turn to you, Lord Roderick. You’re the only one I can trust.”

Tears spilled from her eyes. Seeing her like that, my mind was made up. She was pleading with such sincerity. So, was it true? Had Seraphina really been stealing her sister’s accomplishments? I never imagined she could stoop so low.

“Very well. I’ll help you uncover the truth. Isabella, you’re not alone in this.”

I took her hand and promised my support. Then, I began secretly investigating Seraphina’s activities.

But Seraphina left no evidence. Nothing about her behavior seemed suspicious. She still carried herself with effortless competence, appearing to run parties entirely on her own ideas. In meetings, she gave precise instructions, and the staff trusted her implicitly. Just as I started to doubt Isabella’s story.

“My sister came to me for advice again.”

One day, Isabella approached me, looking sorrowful yet strangely excited.

“It was about the upcoming grand social party. She asked so sweetly, ‘What do you think?’ So, I told her my thoughts. And then, once she’d heard everything, she left with this satisfied look. She’s going to use my ideas again. And once more, she’ll take all the credit.”

Come to think of it, there was indeed a major social event coming up, one Seraphina was spearheading. She had stressed how important it was, claiming its success would elevate the Vandering family’s reputation.

“I’m certain she’ll choose this exact decoration scheme—white and gold, with roses and baby’s breath.”

“How can you be so sure?”

“Because it’s an idea I came up with and foolishly shared with her. My sister has always copied me. This time will be no different.”

She went on to predict other details; the menu, the music. If true, we’d have proof on the day of the party.

If Seraphina really was stealing her sister’s ideas, I’d have to reconsider our engagement. No, more than reconsider, I might have to break it off entirely. With that in mind, I prepared for the worst.

Then, the day of the party arrived.

As I surveyed the venue, everything matched Isabella’s predictions. The decorations, the food, the music. Every last detail.

“So, it’s true. Isabella was right all along!”

I was convinced. Seraphina had indeed been stealing her sister’s ideas and passing them off as her own! I had seen it with my own eyes. There was no room for doubt. This couldn’t be coincidence.

With that certainty, I confronted Seraphina and ended our engagement. This was the right course of action. She was the one in the wrong, and the entire social world needed to know. That’s why I had to condemn her publicly, here and now, where she couldn’t escape. The truth deserved to be exposed.

And Isabella, she had bravely helped me uncover that truth. She deserved something in return. No, not just something she was the truly capable one. With her talent and creativity, she should be the one overseeing future events. Someone reliable, sweet, sincere, and gifted—the perfect woman.

So, I proposed to her.

And to my delight, she accepted with a smile.
