Why do I get the feeling the assassination has to do with the woman who is infatuated with the duke. She must have used the duke's knight to carry out the killing. ML indifference attitude towards FL during their first life could be due to misunderstanding caused by that woman or she did some spell on him and the duke's knight to manipulate them. She probably also work under the order of someone else. If ML was truly under a spell, FL death must have broken the spell for him.
