My Soul Returned to My 17-Year-Old Body, and I Use the System to Stir Up Trouble Everywhere!

All pairings are possible, quick! (More or less, this was probably, maybe, sort of where things were headed... right?)

In my thirties, I kicked the bucket while still young, and most of my memories vanished because of a System called Pandora. I vaguely remember having a bargain-bin husband, who was by my bedside when I died. As for who he was, I can't quite remember. In the blink of an eye, I wake up in my seventeen-year-old body?! I've even been bound to this System called Pandora. Isn't that the gemstone I was searching for in my teens?

There's only one truth: if I follow the System's plot and complete its missions, I can earn points to buy all kinds of strange... things... (??? Why would I buy all kinds of strange things??!) This time, I'm going to uncover every unsolved mystery from back then!
