I think he misunderstood her reactions towards the priest as a sign that she was already in cahoots with the temple(?) Like. Why pretend to be so in love with me and enter this family when you already have a man in mind and a grouo that protects you? Are you here to deceive me? Like that?
All of the above and also he understood the ancient words if love that were uttered during that meeting with the high priest, so he thought that MC was like in love/relationship with the high priest
Wait I don't understand what they're arguing about before. What does Hades mean by betrayal? Can someone explain it to me?
