From a background character to the guardian of the marquess's heir

I was supposed to have died in an accident but when I opened my eyes, I found myself inside the pages of my favorite novel!And the worst part? I wasn't reborn as the heroine or even the villainess but as a completely insignificant side character.According to the original story, the noble couple I work for will soon disappear, and all the servants will be dismissed afterward.I knew exactly how it was going to play out, so I told myself:"I'll just live quietly, freely, and comfortably in my own way."But things didn't go as plannedSuddenly, and completely against the original plot, I find myself in charge of the marquess's children, who were left behind after the tragic accident.I've become their guardian, even though I was never meant to play this role!Even when I tried to walk away, I couldn't ignore their innocent eyes and their need for comfortSo I chose to take on the responsibility, leading them on a journey filled with surprises and challenges.
