She is also jealous of their relationship and wants them to break up. But there is no soft corner for her in Kazuya, as now he was well aware of her different personas. Despite her not being around or with Kazuya, she went out of her way to get more knowledge about him and his new girlfriend.
Kazuya and Chizuru Mizuhara

We see that at the starting of the manga Kazuya decides to use an Online dating app and rents a girlfriend for himself. The girl he rented, Chizuru Mizuhara, was very beautiful and attractive. He somehow thought that she was inauthentic and gave her low ratings. Chizuru berates him for that then he realizes that Chizuru is way meaner than he thought.
We see that Kazuya took her to her grandmother, who was hospitalized and she really liked Chizuru. Despite him saying that she is very mean, he took her to each and every family function and was attracted towards her from the start.
He also ranted about his feelings to her but he later said that he was lying, which got Chizuru angry for saying those things so casually. The same is with Chizuru, she is also very fond of him and I won’t be surprised if they did end up confessing to each other.
