tbh I LOVE PEOPLE LIKE YOU!!! i struggle a lot with like understanding what characters are trying to say and analyzing the deeper meanings so whenever i see people (like you) in the comments who actually explain whats going on and in a way that i can understand i genuinely feel like jumping around with excitement
its honestly so nice seeing people elaborate in the comments because then im able to understand whats actually going on and im not left confused!! thx so much for this explanation of what hayden was talking about, i am like. FINALLYYYY UNDERSTANDING IT LOL
While it's true their original agreement he doesn't lose anything (monetarily), Hayden at the time didn't lose anything either because he hadn't developed feelings for Brett. They both satisfied their primal urges. Brett was there for him every time Hayden was in rut. He tries his best to come back ASAP after his away game & even though part way into it he realized his injury from the game hasn't healed yet/ or that he was more injured than he'd thought. So his end of the bargain is that he gets to get fucked ROUGHLY by an alpha who's willing to be with an alpha. And Hayden gets to take out his overly strong sexual aggression that no omegas can deal with. So yes, initially it was a mutually beneficial relationship. For Brett he thinks that treating Hayden well, such as gifts, & taking him to the family function & introducing him to the producer, & asking him to come to the after party, was as close as he was willing to go. Hayden starts to feel like he's losing out, though once he developed feelings. The one with the feelings ALWAYS loses no matter what.
hayden recognizing that brett likes this "give and take" thing bc brett doesn't actually lose anything from giving the stuff he usually gives (bc he has so much of it); hayden appealing to brett's way of thinking and being like an ACTUAL equal give and take would be you giving your feelings (Bc then brett is ACTUALLY giving something in this exchange - also more romantically, hayden wants his feelings reciprocated <3)
meanwhile as someone who always wants freedom and likes being in control brett hates having his choices limited, which is why when he hears this his instinct is like "are you trying to force me away by putting things in such forceful terms?" so hayden proving that NO he's not trying to force brett away by MAKING OUT WITH HIM but then giving him the nipple pinch to say "you're not off the hook yet" DELICIOUSSS
