Oh yeah I totally forgot about him no we're not excusing chase's bad behavior nor babying him. It's because of all the trauma and his parents negligence that led him to being that. Ashley, his father neglected them emotionally he hates his children who's similar with him just like being a dominant alpha cz he thinks being one has mental illness. He probably favors bliss the most.
But that's exactly excusing his behaviour... .lol
You are not taking into account that he is a manifested dominant alpha.
Chse is totally aware of what he is doing. He even explained why he tried to shoot that paparazzi. Chase is a massive asshole to everyone else aside Josh and he is violent, and even him he tried to kill twice. There was a reason why they couldn't find any bodyguards who wanted to work for Chase.
Oh, and Grayson is an selfish asshole, and his "help" can be really dangerous, but he at least doesn't know what he is doing. Which doesn't make it any better for his "victims".
So considering that none of them is a green flag.
And about the kidnapping, did you forget? He only returned the favor, since it was Dane who tried to kidnap Grayson for Josh in the first place.
In Dane's eyes Josh was their matchmaker.lol
If you consider only the pairings, there actually is something that makes Grayson greener to Dane and the other couples I read of: his love became selfless at one point.

Y'all are funny af wdym green flag??? defending Grayson and shit I've read the novel already whatever the fuck his character development is he's a shitty brat still. He literally poisoned his mother, pushed chase off the stairs, the main reason why chase is having a hard time growing up is because he's a big fat bully who has mental problems. Chase is probably the decent child out of 5 of them. Also the fact that he keeps pushing Danes nerves every single time he kidnapped Dane as well. Idgaf about spoiling anyone.
