How the kids feel about their assigned parents:
Urie: has a lot of respect for Amon as an investigator and a man (may or may not have the tiniest bit of admiration crush on him), doesn't like Haise. Will do chores if Amon asks him, mostly ignores Haise.
Kurona: Amon is the last person she sort of respects, Haise frustrates her but she works well with him (additionally, she hates Quinx Squad's proximity with Suzuya Squad. she bolts whenever they come over)
Saiko: she just likes both of them a lot
Shiragin: he respects both of them a lot, but feels more comfortable confiding in Amon, since he's a lot older than him, unlike Haise (think Fura).
Mucchan: he respects Haise as his teacher and supervisor + very crushing on him - but he's scared of Amon: very big and buff man who speaks mostly with his eyes? big no from him.
A little bit about the parents as well:
Haise: he wishes Urie would open up to him at least enough to work together + he gathered that Kurona knew his previous self but they're not allowed to talk about it
Amon: at this time, he's still doing very badly and doesn't actively tries to connect with others, which is why he was placed in the Château in the first place. doesn't get why Mutsuki is so jumpy but he leaves him alone as a result. Following this idea from my other fics, he recognizes Urie's name and since Mikito took care of him before he died, he tries his best to take care of Kuki in return - he thinks he's doing a bad job but everyone is ":0 holy shit Urie listens to him wtf". He's pretty awkward around Shirazu, especially at first. Saiko adopted him immediately and she doesn't mind if he stays silent while she rants so they get along well + they both like eating + he actually tries her video games when she proposes. About Kurona, she's there because he advocated to get her out of Cochlea so he tries his best for her. he had a bit of trouble adapting to her new personality, constantly comparing her to the one he used to know but he's gotten over it now
