I think it depends if Mona picked up on the fact that Kurumi and Naoi are into each other. If she did, then she might partially be doing this to get to know her sister's future girlfriend better, since Mona clearly admires Naoi a lot, so of course would also think anyone her sister's in love with must be amazing as well. Also, Mona blushed similarly when pointing out that Kurumi liked Naoi last chapter, or in the flashback while holding Naoi's hand.

Though whether or not Mona did pick up on Kurumi's feelings for Naoi, she currently only has a very superficial understanding of Kurumi at this point. And likening her to an idol means her opinion of her has nowhere to go but down. Like for example, if she finds out about all the things that happened in volume 1. She might eventually deem Kurumi a bad influence on Naoi and want to separate them, thinking Kurumi brings out Naoi's violent side.

Though I wonder how this volume will play out, since with the school festival this weekend in the story, and Kurumi's mom now imminent, that seemingly leaves very little space for Mona's plot to really expand. And of course there's the fact that last chapter established much of Mona's behavior being due to trying to fix whatever her home situation is. Meaning anything she currently says or does likely has an ulterior motive with that goal in mind. She views Kurumi and Naoi as liferafts, even if she does genuinely like them.

Very good points

Very good points

Thanks. I also thought of something else. Kurumi might interpret the request as Mona trying to replace Naoi as her older sister with herself, which could actually make Kurumi angry. After all, it was Kurumi who was so optimistic about Mona having no ulterior motive and only wanting Naoi to live with her, but now it looks like she was being naive and Mona does indeed have an ulterior motive. While readers know enough to assume that the motive is at least sympathetic, Kurumi doesn't, meaning she could mistakenly think that Mona is just being spoiled.

Considering that Kurumi knows how much Naoi was hurt by her mom abandoning her and only taking Mona with her, which she thought back on last chapter while walking with Mona to her house, Kurumi might actually snap at Mona next chapter, thinking that her actions are very hurtful to Naoi, mistakenly thinking that Mona is wanting to just abandon Naoi again.
