We never sat YH play with any guys hearts. It just said that there were many guys who fell in love with her, but that doesn't mean it's HER fault that they fell in love with her. It never says she seduced or encouraged any of these men; it's probably just like in any other reverse harem story where the guys just fall in love with the heroine. In the story recap we only saw YH interact directly with her master and given what a dick he is, its no wonder she left him behind.
If you read the novel then you would know that YH really did make a harem but never accepted them including her mast because of a spoiler and she left cause that that same spoiler. YH could of have rejected the guys but she just string them along until the in and in MM over take body timeline MM was only in a relationship with the master but YH ruined it hence the end of the worl buf MC needs to fix ,reason why I pity MM is because she just want one guy and YH wont let her but MM is not so innocent since she went on a killing spree and i dont think it was mention but after losing to YH in original timeline MM was raped by multiple men cause she can boost their cultivation and died a sad death while in every timeline YH have a happy ending ehile leaving victime and by happy she went back to spoiler
at first i pity mei muying cause yue hangxing is a slut. YH is constantly playing with guys hearts and left them hanging cause of a reason that will be revealed late and it is not a good reason too so no surprise MM getting jealous and is constantly picking a fight but then MM is such a bitch steal other people lovers like seriously didn't you not learn from YH. MM still got a bad ending though but the slut YH go an ok ending and their master is a bloody idiot
