“Ah… I still have to finish the annual event schedule and write up the meeting minutes…” I woke up inside the body of an extra—twenty years before the original story even begins. In the family, I was despised, my fiancé cheated on me, and in the end I died pointlessly in a carriage accident— ‘Huh? Did I regress… ten months before my death?!’ The moment I returned, I bolted from both my family and my unfaithful fiancé, and ended up as a kindergarten teacher, reviving a failing school… but then— “Hey, you’ve got no class.” “Did you just bark that at me?” The bratty male and female leads—who I shouldn’t have met until ten years later— are already here, bickering nonstop! And if that weren’t enough, the emperor, the mastermind villain, the wicked lady, and even a bunch of big brothers keep showing up under the excuse of “counseling sessions” at the kindergarten?!
