Transmigrated Villain? Nope, I will Enjoy this Afterlife!

Most normal transmigrators have some type of horrible childhood they overcome or some type of monstrous trail they must defeat. Plus, they are normally murdered or die from some freak accident. I am not this type of transmigrator. I had a loving family that worked hard to grant all my wishes. I grew up and worked a normal job. Got married to a wonderful man and had great children that eventually grew up and had children of their own. Then I died peacefully in my sleep with no regrets in my life. So as a seemingly normal and boring transmigrator why am I reborn as a baby in a light novel I read online and never finished because the author went on hiatus and never came back.
