ML is the 8th prince, Xuan wang, Feng dye ( in mtl)... like in that other novel, Tyrannical wang’s beloved wife, ML plays the public’s perception of him as a dandy playboy to hide his strength, but in this novel his emperor father plans for him to inherit the throne, idk what happened in the 1st life that made ML go and eventually went missing in the Nanban(?) kingdom. There seems to be a secret behind his concubine mother’s identity and death but since i jump chapters, still looking for it
