I’m just saying this because it’s my own opinion so I'm not sure, but I believe that the ML might not actually be the child of an affair but a different person or the fl is not the biological child of her father as claimed. The two characters will probably be in a relationship if this going in...
Thank you @blueoddog, but I just want to know one more thing. Is the ML similar to the scum Emperor in Remarried Empress or Yialos from To Be You For Just One Day?
