Tada no mobunanoni, kōshaku-ka atotori no hogo-sha ni narimashite

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 wasnt 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: Ill just live quietly, freely, and comfortably in my own way. But things didnt go as planned Suddenly, and completely against the original plot, I find myself in charge of the marquesss children, who were left behind after the tragic accident. Ive become their guardian, even though I was never meant to play this role! Even when I tried to walk away, I couldnt ignore their innocent eyes and their need for comfort So I chose to take on the responsibility, leading them on a journey filled with surprises and challenges.
