This is the opposite of what you wanted- an ML who goes back in time for the FL (mc is the FL) but it’s an amazing story so I’ll put it in case ur interested

Anyone know some romance where the FL wants to save/protect/care for the ML? Like reincarnates in to a novel with her favourite, or goes back in time after her husband dies, etc.
