Taking Charge! Isekai: How I Became The Beloved Imperial Princess

This is not a webnovel, this is real life, so how in the hell did I get transferred to a different world after I died! Just a moment ago I was going to buy some groceries at a convenience store and after I got stabbed by a psychopath on the street, I died and the next moment I find myself in another world where I am the imperial princess! You'd think I won the lottery, in some ways I did, but let me tell you, I'm in way more than I bargained for. I may be loved by the Empire, but my family is certainly giving me a run for my money. Will I really be able to survive in this world? Especially when all I want to do is teach my good-for-nothing family a lesson? Screw them! I'm going to ruin their lives and teach them what this five-year old princess can do!
