Because that's a big MISCONCEPTION about Grayson, and a mistranslation. Chase was a rude brat when he was a kid, Ashley had to be strict with him, bc he was already a little mad dog way before he got his trauma. That's why he keeps getting picked by Grayson, most of the time what Grayson does to him isn't bc he hates Chase but either he's trying to help Chase or preventing him from doing something bad.Grayson never actually tormented Chase intentionally, it was just way worse from Chase's perspective bc he was a sensitive child who overthinks a lot!
What actually happened when they we're kids was Chase was constantly getting pheromone injections which basically is a way to release pheromones without fucking someone but they take a toll on the body physically and mentally, it became severely unhealthy for him. So by the time Chase took an injection again and fainted, Grayson came to him and PRETENDED to act like Chase did it with a dog to force chase from not continuing the injection so it doesn’t harm his body and Chase can be healthy.

Just want you to remember this mf made his little brother think he had sex with his dog and fucking traumatized him. So I expect him to be treated by this omega as a fucking rag doll and be thrown to trash
