She regressed and managed to still live a miserable life. Amazing.

She regressed? You mean transmigrated. A regressor knowns the past. She doesn’t. She’s no different than a normal person other than her knowledge from modern times

My apologies. I thought that an adult becoming a child... would have regressed. But here, let me make it up for you: "She transmigrated and managed to still live a miserable life. Amazing."
