It's been 8 years since I was transported to a trash game isekai. As a level 999 hero, I finally managed to return home where my precious little sister was waiting. I was planning to sell the treasures I brought from the other world and live comfortably, but— "Don't move! Hero Association!" I got arrested for not showing up to work for a while. Oh right. I was originally a D-rank hero bound by a slave contract. But why is this A-rank hero suddenly becoming obsessed with me? Just leave me alone.
