I really don't get how people think Heath is better for Anton.
Literally none of that means Heath is better for Anton. This is a story about Arwin and Anton, so at some point, Anton will more than likely have a chance. Plus, we don't know exactly what it is that Arwin feels for the dad. Even if it is love, things like that can change.
It does, but more than likely it's going to end up Anton and Arwin. Lots of people are on the side of Heath based on his looks. We do not know much about him or his personality to say he is better for Anton.
Seems to me like you're confusing two issues; why people in the story might say Heath is better for Anton, and the other being whether or not plot-wise that would be true as well. Those are two separate issues. I think there are many reasons why certain characters in the story might think Heath is a better match for Anton. At this point both Heath and that lady knew more about Arwin and how he feels than has been revealed to us or even to Anton. We can only strongly suspect. But the story is certainly constructed as to surmise that Arwin and Anton do become lovers and end up together.
May be heath is better for him but u know like father like son both has same tastes..
