The leaders of the world have decided their problems can be settled by giving the nations of the world a truth serum and forcing them to spend the night together. A night escalates into a week. No one is happy, since the doors are locked and the only way to get out is by smashing a window, and even then, they'll have to get through the "security" their bosses were so kind as to set up. Everyone's frustrated, but in the end, things to take a turn for the better.

You don't know how or why, but you've been isekai'd into the world of Jujutsu Kaisen. Although your first instinct is to stay far away from the plot, you've been blessed with an abnormal amount of cursed energy, and for better or worse, you find yourself sucked into the storyline. You decide that you may as well use your newfound powers for the greater good, and if you're lucky, you might succeed in rewriting some of the characters' fates. But it turns out that your presence in this world is even bigger deal than you first thought, and soon, everyone wants to make you theirs.
