Brett invades Hayden's house with the intention of seducing him, so that he continues with their agreement to be sexual friends. Hayden even gets carried away (to a point) as he likes Brett and is in heat. After noticing Brett's cold eyes and the game of seduction he plays (as he had already done at the charity party), he kicks Brett out of the house in just his underwear. After that, Hayden suddenly starts to remember the events of the night when Brett uses the safe word. He remembers that Brett was affectionate with him and he marks him.
Oh, thank you for answering!
I get that Hayden is bonded to Brett, but it's one-sided, right? I didn't get why Brett almost threw up in this last chapter (not in the flashback)
Because Hayden is an alpha with pheromones so strong they can even kill an omega! As Brett is an alpha, it doesn't go that far, but he often gets sick... in other words, Hayden has the power to massacre the omegas and even hurt the alphas if he wants.
I'm always so attentive to the details but I just got lost in this story. WTH is happening between them?? （/TДT)/
