We have got evidences of his malevolence. I don't deny facts when I see them.
I kinda preferred him when he was uninterested by her: his mouth was shut most of the time. He is the one who became complacent.
He sounds very ignorant; even the princess was skeptical about the idea of eating vegetables and exercising regularly. I feel like diet/exercising is so mystified.
I don't even see why he is displeased about her newfound routine nor how is he aware that she eats more? I would be concerned if someone is stalking my meals while leaving at the other side of the country. (⊙…⊙ )
Calling Isaac a B@stard? This is harsh? He was always galant toward her, never badmouthed her or cheated on her. He even declined the avances of that Julia. Mariage out of love is pretty uncanny among nobles. He treated Grace with dignity despite her not matching his beauty standards. Are you hating on him because he is willing to marry someone for the sake of duty? The fault lies on Grace's parents for not managing her weight properly, leading to have her public image compromised and distorted. The Palace raised a delulu and failed that child.
