@Whatever It's probably because they know the game/story/past, so they're using the knowledge to their advantage. Remember that in these stories, the transmigrator/regressor, uses the future/storyline knowledge that they have to seek out people that'll help them acheive their goal. Estelle sought out a duke for a contract marriage (very common in these stories), and Chloe was a character doomed to die from an illness (also a recurring theme in these stories). They both needed a divorce, so they used their knowledge to seek out the person they knew would be best.
