GOM + hanamiya + hayama finding out their s/o was a ghoul (like from tokyo ghoul)
Kuroko always had his suspicions, but once he finds out, all pieces would come together and more than feeling afraid, he would be curious. He heard of ghouls, but he never met one, or maybe he did, he would never know, so every now and then he would ask his partner a question or two regarding their diet, lifestyle and anything that he wondered since he first saw the news about a ghoul.
Kise would be terrified yet excited at the same time. He would begin to be cautious around them, but once he’s sure they don’t want to harm him, he would be a bit more relaxed, but still a bit cautious. Once he gets used to them being a ghoul, he would be the same Kise he was before and would even joke about some things that someone mind find inappropriate.
Midorima would be thrown off and would most likely keep his distance for a while to figure out how he feels and what he wants. If he cared for and loved his partner truly then he surely wouldn’t mind letting them back into his life, especially if they prove themselves to love him. Of course some rules would be made that would make both comfortable enough to stay together. But if he couldn’t be with them, he wouldn’t run around the bush and tell them exactly how he feels.
Aomine wouldn’t exactly care if his partner was ghoul or not, but he would be careful around them at certain time. Despite that he would act the same like before. Every now and then he could ask a question regarding their life-style, but other than that it would be more the same. He would be pretty chill and relaxed, but if anyone was badmouthing his partner then he sure as hell won’t stay by and watch.
Murasakibara would be more terrified that they can’t eat food and snacks like he does than being scared. His questions would definitely be more about food, how often do they need to eat, if it differs from humans and such.
Akashi like Kuroko also had his suspicions, but unlike him, he would ask them straight out, without running around the bus any longer. He would feel a bit anxious and despite looking calm and composed, he would think more about their well-being and life as a ghoul. Some things could change between, but nothing too drastic, though if his father knew about their relationship, he would make sure no one finds out of them being a ghoul unless they wished differently.
Hanamiya would somehow be thrilled, so he could come up with remarks every now and then that could either make them uncomfortable or just make them want to smack him upside down. On the other hand, he wouldn’t entirely care if his partner was a ghoul or not; as long as he had benefit from them is all that he cares for.
Hayama would be excited and there would be no ending to his questions. He would really be curious how ghouls are different from humans. I don’t believe he would be afraid or terrified, but he surely wouldn’t like for anyone else to know about them being a ghoul, because he knows they aren’t entirely welcomed in the city.
