A white haired heroine........sent to a distant fiefdom and became a loved lord...her stepsister wanted her betrothed, who was a prince.

Thinking of a manga where......a king kills his empress and her family and puts his lover on the throne instead but the sister of the empress is the one who isekai'd and takes her sister's place to prevent the death of her family. All I remember, I'm sorry

I am thinking of a manga with a green haired saintess who knows she is in a book, and a girl who in the original plot, comes from another world but is also somehow related to the saintess and is a saintess herself....... ideas on title?
