I read several novels and manhua and watch donghua with multiple love interests like this one he has 6 wives + 1 future wife which is Murong bingyun I totally agree with you because of female watchers harem anime or donghua adapted to live action didn't happen or made in a low budget like this one but despite being low budget I love this one
Sorry girl this is not your typical type drama where male and female lead has to save each other and sacrifice to each other lives in name of love This drama is about a guy Qin chen how he takes revenge from his lover and her boyfriend for betraying him and if they follow donghua so no romance but you can see some sweet moments between some of the girls and him originally in donghua he has six wives and 14 love interests and one girl murong bingyun future of Qin chen and also his cousin Qin yun and he is considered to be badass male lead who hasn't like lost a single fight in donghua but I am not sure about this one
There is also a donghua of this drama name Martial Master and this is 45 minute full series donghua version is a harem one Qin chen has multiple wives + love interests
