The casting for this isn't easy and nobody knows if those rumored are just rumored because their visuals fit the description. It's a fairly explicit arranged marriage novel and the FL is described as a petite, smart, strategic beauty age 14. The ML is a 1.9m warlord who marries her to destroy her and wants revenge on her family for killing his father and brother, but sets aside his anger due to their love after many misunderstandings.
The popular choices for the FL are Song Zuer/Chen Duling due to their visuals, build and smart appearance (the ML is a prisoner of her beauty even though she schemes to protect her family against him), anyone who isn't pretty enough will be criticised because of how OTT the FL's beauty is described in the book. She is described as thin but peerless in appearance.
The age 20+ towering ML is like Xiang Yu or Sun Ce (Google actors who played these roles) since this novel is set during the Three Kingdoms era, a tall skilled warlord who falls for his new wife but can't fully let go of the hate toward her family. Very few actors fit the height required, ideally it's someone built like Peng Guanying (too old) hence Liu Yuning is rumored because of his build. Ideally it's someone like Chen Xingxu but he may not want to do another role like Eastern Palace. Not sure if the rumored actresses and actors would even want to do the love scenes.
This novel is popular in China and there is buzz about the casting after the IP rights got bought director Deng Ke, you can read the translation which is halfway done https://www.novelupdates.com/series/the-marquis-is-innocent/ I don't know why the English title is like this because the marquis is anything but innocent and the novel needs to be censored heavily to air.
