Isekai'd (No Longer Layabout)

You aren't from this world. You don't remember what happened, but considering you got shoved into a body that wasn't your own, you have to assume the person you replaced is in your body... or your old body died. Either way it's not exactly the biggest thing on your mind now. Mostly because you got shoved into the body of the fourth in line to the throne for House Tianhan Royal Family in the Yinhan Empire. The layabout that literally everyone looks down on. Before you occupied this body, the person who had before you ruined just about any good will you might've had. Drinking. Partying. Basically living however they wanted while muddying the name of the royal family. Even your own father, the emperor, had fully given up on you and sent you to some backwoods territory to keep you out of the way. But... that was the original person occupying your new body. Will you continue the trend and live a life of luxury and leisure? Maybe the new mind in the body is a terrifying assassin, or a hero from another world. Maybe you'll revolutionize technology and healthcare. Only one thing is for sure, people are never going to expect the 'layabout royal' to suddenly stop being an embarrassment. ~~ Can't remember who it was that requested I make a scenario with Chinese style names, but thank you for helping me keep things varied. I probably didn't do enough research, but I did try to do it justice. It's kind of fun to have a request that wasn't so specific. I got to find an idea in my list that would fit it, and this one seemed perfect. Hope you all enjoy :D ~~ Added Auto-Cards, and Inner Self options, as requested. Thank you as always to LewdLeah for the amazing scripts, and if you'd like to request them on one of my scenarios that doesn't have it, I add the options happily upon request.
