Help finding this manga?

So it was either a Yaoi or a Shounen ai (pretty sure it was Yaoi though). So this dude (uke) gets reincarnated as this prince or emperor dude who had just attempted suicide. Gets treated like shit by this General I think (seme). I think the seme had red hair or something. It turns out that the seme is actually the real prince/emperor dude and that the uke was just a place holder. I don’t know if this was like japanese or chinese though. Anyone have any idea though?
