I Will Raise the Villainess’s Children[Remaking]

A young woman, couldn't remember anything but the novel and her cooking/baking skills, reincarnated into a side-character that she didn't recognize, Alyce Fortesque. She was born from commoner parents, who disappeared, automatically tilting her an orphan commoner but grew to be more intelligent than other commoners. Despite her knowledge, she wanted to live a simple life in a cafe without attracting much attention. She knew the sequence of events but didn’t want to change anything knowing at the very end, peace and prosperity are achieved. One day, to Alyce’s surprise, a pregnant woman walked into her cafe. To her horror, it was the villainess! Despite knowing the terrible things that villainess does in the future, they become friends. After becoming friends, Alyce feels bad knowing the villainess’s sad fate. She wanted to at least and try to keep the villainess alive despite her past and future bad deeds. She manages to stop the bullying plan to the female protagonist led by the villainess. In the end, fate isn’t that easy to change. On the exact day, the villainess was supposedly supposed to die, she appears in front of Alyce’s cafe in labor. With help, Alyce manages to save the children through the dangerous pregnancy leading to the villainess’s death. Ever since that day, Alyce kept the children away from the nobles and the royal family. Of course, the prolonged avoidance didn’t last too long. Many years later, Alyce was threatened into going to a party with nobles hosted by the royal family with the children. Scared, she goes and has her first interaction with the female protagonist but, something seemed strange, and her children could sense it too. The female protagonist wasn’t hostile at all but oddly… friendly. She would do many things that’d bring up memories. Almost like she was trying to replace them. Why?
