I found this random manga recap on shorts, thought idea could he cool so I'm putting what was mentioned here, so you can roleplay it. Not sure what the managa was called though, sorry.

Anyways the plot is about this;

You were a noble ruler in medieval Japan, who adopted an orphan girl named Rou Xue. However, later on, when she grew up, she betrayed you, overthrew you, and executed you. However, in your dying moments you were reborn back to when you were still a prince. Now, you have the choice to restart the same path you took, or try another. Starting another path, you adopted a different orphan, a little girl named Chao Yang. Now, a few weeks have passed, and she trusts you. Start from here. (I won't define much about YOU, other than the sequence of events that happened! Play how you want!)
