I always felt a bit sorry for Kana that she only got 1 compliment
Miku got a poem and was complimented into masturbation mode.
Hinata exchanged praises with Sou and he also touched her.
And poor Kanaria got served a re-run, huh?
So you might think... but you should look closely at this chapter and some events that follow later.
But first things first - it's true that Kanaria likely expected more but it was her own fault for writing exactly what Sou would praise. Had she not done that, well... but look, she was still satisfied - her face on the last picture tells it all. Kanaria obtained something here, I already mentioned that earlier. Now, what would that be, you ask?
Simple: a "virtual holy relic"
Let me elaborate: unlike Miku or Hinata, Kanaria was clever enough to record Sou's voice when he praised her. She saved a compliment from him. Not only that, it's one where he used her pet name "Kana". Oh but he uses it all time, so isn't that just insignificant? Far from it:
A boy addressing a girl by name is extremely rare. What about her given name? Haha, good joke. Her pet name? What drugs are you smoking?! Okay, seriously, the norm in that world, even for female family members, is way different. Original Sou for example NEVER used the given names when interacting with his sisters. He addressed Sumire rudely with "hey" or "you"... Isekai Sou also uses Hinata's and Miku's given name, but for Kanaria it's her pet name. She got a record of her dream guy praising her with her pet name - you bet she will make this her lullaby, she said so herself.
Now here's the thing. Where did we see something similar? The scene happens later in the story, but Kaede Kakizaki does the same thing (recording her phone call with Sou). The stimulus of hearing his voice so close and using her given name turned Kaede into damaged goods. Kanaria in contrast remains sane - she's her usual (albeit rotten) self even after two days/nights were she used that recording to lull herself to sleep.
I'd argue this hardened Kanaria's mental firewall. Keep in mind, she saw from up close what happened to Miku and she is fully aware of how dangerous Sou's words and deeds are. She knows the effect from personal experience. That's also why she warns the ignorant Class A girls about it on Day 3 morning.
There's another notable thing - Kanaria herself mentioned that, unlike other girls, she is unable to create erotic fantasies to distract herself. It's a technique girls of Konoe Gakuen use all time. That said, Kanaria is forced to endure mental stress and keep her cool without delusions. Showing a calm outward appearance despite that while being a huge pervert on the inside? Yup, this girl's got her act together - her mask isn't perfect, though, she failed to fool Sumire.
And then there's another thing Kanaria gained from this event. She gets greedier and bolder. She wanted to be Sou's wife right from the start, but now she will do what's necessary to achieve this. I daresay it's to a point where she takes risks and grabs chances whenever they appear before her because she doesn't want to be outdone again. Of course she wouldn't openly confront her two friends, but other than that, anything is fine.
If you don't believe it, see the most recent event where she risked her dignity and wellbeing to get a taste of Sou's cooking. She tries to act before others can. What happened? It sends her into an alternate realm but since Kanaria is normally used to fight lust without delusions, she was able to recognize that world as fake. And then? Instead of just breaking free, what would be the normal reaction, she used that world like a lucid dream - just for her own enjoyment. And once she was satisfied, she broke out by her own will. Sasuga Kanaria.
This Ojou-sama may act rashly at times and she's still a bit awkward but she's a nevertheless a serious and crafty one who uses what she has at hand. During the home visit Kanaria agitated Sumire's hostility by calling her "Sister-In-Law" - this is Kana making it crystal clear that she considers Sou as her husband and herself a part of the Satou family... and when she reveals Sumire's "Violet" account and praises it openly, she mitigates Sumire's anger.
The other girls better watch out for this one.
