@Pipi He only noticed her when she showed her worth, if he truly loved her he would immediately take her in to take care of her when her father died or atleast visit her once in a while. They live in the same home
@Kue7Pandan to be completely fair he is a busy very man. On top of that letting her reside in the main house like he did is actually a kindness when most nobles would have kicked her out the moment her dad died.
