Their relationship?

TLDR;

Achilles 'humiliate' her (similar to original myth), and (just like how Achilles portrayed on other media) Achilles not even showing any sign of regret for humiliating her.

That's why Penthesilea in constant rage when it comes to him.

Hector (FGO) on other hand, is just like Blackbeard, he is not interested keep living on the past, thus he is more friendly. As shown by the lines, the rock thrown by Hector is done as act of friendship, allowing it to bypass Achilles invul.
