If you dislike a character, you can simply skip them since no one is forcing you to read it. Grayson and Dane are the first characters the author conceptualized when building this omegaverse, they are not side characters the author randomly choose to write more after kiss me of you can. You may like a character more but who the author is interested in writing and developing is her choice.
Also, so many people bring up the brother point while compelely missing the context. Chase asked if Grayson would have sleep with their brother if he went into rut and their brother is there, which Grayson said yes. As immorally as it is, this is the reality of this world where pheromone especially in heat/ run makes people completely loose control. We saw the same thing happens with Chase and Josh's first time and even Grayson and Dane's, when they are under pheromone influence, they can jump on literally anyone. Grayson's intention has always been emphasizing that releasing pheromone by your own beforehand is always a better choice than letting it build up and try to keep your mind and moral straight under pheromone. The author even has to tweet herself to explain this because people keep misunderstanding her from kiss me manhwa.
And this story doesnt suddenly make all Grayson's actions all innocent, it provides context on how and why he acts the way he is, how he interacts with other people and eventuallu how he grows. If you dont want to give him a chance, you can ignore this and let other people who want to do it. There are many other stories about other Miller family members that have their own novel and may get manhwa adaptation as well, it wont stop with just Grayson.
'prefers to fuck their omega youngest brother over a dog' pfft where was this mentioned? most of the people here have read kiss me if you can if you don't like grayson it is completely fine but fuck off from here you chase fans spread negativity everywhere even in omega brother novel u all hate bliss because of chase
you're telling me that bastard of a brother who "prefers to fuck their omega youngest brother over a dog" has a love story? the very root cause of chase's ptsd toward dogs? grayson's a fucking annoying ass brother (and a character as well) and dane (the one who help yeonwoo in kiss me liar) is such a good person.
grayson deserves to be with a person whose just as fucked up as he is. and literally, someone said "give grayson a chance". oh ho bitch no!
emma bailey (joshua's younger sister) deserves to have a story of her own, not this monstrosity i call grayson miller. what was going on with the author's mind? why would they even think " hey, let's give this bastard a love story. and let's make him a couple with a person whose completely different than him".
I TELL YOU, READ KISS ME IF YOU CAN BEFORE YOU READ THIS DISGUSTING MUTHAFUCKING STORY!
