I like the way the manga portrays social stratification, even if it's anything but subtle. Kazuki is such an adorable MC too; it's interesting how she focuses on the emotional intimacy of erotica rather than the physicality. She's a hormonally repressed teenager, but at least she has standards.
I hope there are more nuanced discussions on gentrification. I don't think Kazuki's perspective is wrong; gentrification, even if it displaces its local residents, has many advantages, like business investments to stimulate smaller city/town economies. It's just that the stimulation will prioritize the middle to lower-middle class residents over the destitute. I especially like the part where Kazuki notes that these delinquents are smoking and loitering around areas where kids play. It's not like Kazuki has a problem with poor people - she's mainly ignorant and dislikes people without social consciousness (even if that's ironic). However, the social consciousness is about public etiquette rather than economic disparity (even if the poor public etiquette is due to economic disparity).
Moeka is also patient due to her carefree nature. It's a little wild that she'll just have a makeout session in front of a stranger, but she's very emotionally aware. She recognizes Kazuki is not malicious and never explicitly states that Kazuki is being insensitive (for better or for worse). A good detail emphasized is that Meoka does repay Kazuki. She subverts our expectations; no, Moeka is not a bum who will sponge on people's good intentions just because she is poor. It could have been easy to play as comedic relief, but I'm glad the author didn't.
The story has been good so far in its ability to explore different perspectives. Kazuki is right to feel proud of her father (given that he's not a cliche evil mustache-twirling capitalist). Moeka is right to feel that Kazuki is an out-of-touch rich girl, even if she's a kind, naive teen.
