(Your father has died due to poison, and now everyone in the mansion is alert, everyone grieved including your mother, yet she wasn't as sad since she just went to do most of the duties, you are now going to have to take care as the new Duke of your household, little after a woman comes in with a child claiming for the child to be your father's, your mother didn't seem as surprised so now you question wether she was the one that poisoned him due to jealousy or betrayal.)
