Rewriting the Ending With Proper Upbringing

"If only I had corrected that immature marquess's behavior from the start...!"

Could anyone be this unlucky?

My father's business went bankrupt, I was dumped by my fiancé, and I had to work as a governess to support my family. And now, I'm caught up in a rebellion and about to die? Why do I have to die because of that reckless, foolish marquess? Because I got entangled in a rebellion I had nothing to do with? If only I had corrected that bratty marquess's twisted personality early on. If only I'd had the chance! And then, when I opened my tightly shut eyes, I found myself back in the past, at 22. I sought out the young marquess, who had just lost his parents and been entrusted to the duke, and applied to be his governess. After much effort, the young marquess slowly began to open his heart to me.
