I agree with you with most of your speech.
I do not agree that he is already able to accept any hatred due to his choices but he has nevertheless realized that the status quo does not make anyone really happy.
also her problem with Ruka is not so much having a relationship with her and the possible problems of her character but the fact that even if he wanted her heart he chose Chizuru.
on Ruka then it is a separate matter.
given that I love the character.
in my opinion Ruka is simply the classic person who has felt different from others and with a handicap; this led her, when she discovered Kazuya, to consider him a sort of savior and for this reason she threw herself with all her strength on him.
she was even willing to threaten him in order not to lose his hope of salvation.
(I think) that if the relationship between her and Kazuya normalized also various obsessive and "psychoparic" attitudes would disappear; in the end the big problem for her is that she is constantly competing with Chizuru to win Kazuya's heart and as she also said in some chapters "she doesn't want to lose".
for the rest yes, it is hoped that Kazuya has finally become aware of both her love for Chizuru and that she must take courage to declare herself and stop lying to her family and friends.
but in my opinion this will not happen anytime soon; in my opinion as usual to unlock the thing will have to intervene Yaemori.
However, nothing prevents the author from surprising us one day and letting Ruka take conscience and she decides to abandon Kazuya to finally and definitively push him towards Chizuru.
i use google transalte, if i made mistakes it's her fault. 😅
