I recommend 'My Wife, You Say' to you. Although this novel didn't completely meet the requirements of the title, there was a male protagonist who was also reborn. He also watched the owner of the body and the adopted son of the body die in his previous life, and then began to change his fate after rebirth. In addition, the female protagonist in the novel also had multiple identities and memories, similar to the plot in the title. I hope you like this fairy's recommendation. Muah ~😗
