Probably too much night activity with each four of them or they drove her mad and caused her suicide due to them fighting over her and each caused her over stress or the women around her were envious and caused her demise whether by poison or something else.
Bruh wtf. You have a very vivid imagination. She says that she died from drowning while trying to save a selfish 5 year old boy, who didn't tell that someone went to save him
Also rong (the black haired one) seems to be the one who was going to marry someone else, he exiled her family, and didn’t hold a proper funeral for her. Cuz she said she was going to get her revenge on him. So she purposely chose him to get revenge.
Oml Op's question was why she died, not why she wants revenge. Plus she pretty much hates all her husband's, except her 3rd as far as I can tell. I think ml is 1st husband, just because of Chinese manhua tropes that I have seen in these
why did she die in her past life? was it one of the guys she married? or do they have nothing to do with it. from the last part it looked like all of them wanted her for themselves?
