Ask for the name of a time-travel novel

There was a killer who liked to wear red clothes called Hua Cuo. The female lead had fallen into the water and transmigrated (I think she committed suicide by boat?) The ending was that she wore it back to the modern world and then wore it back to be with three male leads. One woman and many men I've been looking for it for a long time, but I forgot its name. Thank you
The assassin in red seemed to be called Hua Cuo. He used to be gay and liked another assassin A. Assassin A loved the female protagonist very much, so the assassin in red hated the female protagonist very much. Later on, during their interactions, the killer in red's hatred for the female lead turned into love. Not 'Feng Qiuhuang'
