I think.... I just think~, that the will says HER to be WITH him.... Layk care etc. U know what I mean.... And bcuz of dis, after she escapes the palace, the tyrant chases and looked for her to fulfill the will... Just like the one showed at the prologue
Dylan will misinterpret the will as an arranged marriage contract. I bet you that’s what happened. The words are probably something like “may you both find happiness together” and Dylan misinterprets it.
I imagine hes showing her the will because shes included in it now, and her final words of take care of him will be reiterated in a way that makes it sound like they should get married or something
