As I was reading, I thought Satsuki was going to be the one to save the locked up, anger issues, robot teen. It really does feel like a waste for Satsuki, she had more potential for the story, and served as a foil to the main Miina (Satsuki situation could be Miina's endgame after Takuma dies). With what ppl mentioned earlier, the replacement idea could have continued to worked and gave Mina more freedom to do wild stuff like her 1v1 robot fight. Or maybe she has to pose as Mina because HQ gets aware of Mina going off the rails. I would've liked to see how Takuma's family reacted to Satsuki and them take her in, or maybe Takuma temporarily taking in all the purposeless robots and helping them find someone else. Though I kinda dislike the egg robot getting in the way of the main ship tbh, so all of them there could be a nightmare.
From the hints in their dialogue we are given, it seems like older abandoned robots have sentience beyond their initial programming from the their real life experience. But unlike Miina who is evolving/has a bug/etc. they still have to adhere to the "protect humans at any cost" rules, and can only gain satisfaction from helping them (I agree that in this chapter it is morbid). Even though the main couple or the robot club are unscathed, this does feel like the bad end for homeless robots and Satsuki, though they see it as the opposite, which makes things more twisted.
Idk about the main couple SoL vs the robot club droning about ethics sentiment. On the surface, I prefer the earlier chapters and focus on the main couple with the flairs of Miina acting up. The robot club, with them just talking can be boring for sure. The spice, for me at least, in SoL relationship moments can only hold as long Miina's intentions are unclear. Like ya'll were saying earlier, she likes to act like she adheres to robots logic and rules, but given the freedom she has, she chooses not to (hiding it when she can) and gets closer to being truly human like, I guess. TLDR, the main couple doesn't need to be in x amount of chapters, if the world building can relate back to them directly and move the underlying story forward. Miina has the power to truly shake the current world's robot standards if she wanted to. This also sounds like premium copium though coming from me, hoping that threads are followed through in the future, when the complaints in the now of the change of PoV and worldingbuilding are also valid. It does feel like the main ship has been anchored for awhile now.
I think the philosophical robot ethics discussions that people think are a slog, are only a slog because some readers think the new side characters are less interesting, and would rather see Miina and Takuma actions and romance progress first foremost (or for them to move the story forward). What people are missing is that their love can only progress so much until Takuma is taking advantage of Miina, or disserving himself from his uncle and parent's first impressions of their marriage. There's a physical line of past 2nd base that neither of them cross yet, probably for that reason. Even if they are married, even if Miina is different and special, even if Takuma can convince his friends/family/neighbors/HQ/etc. that Mina is different and special; it doesn't change the social and legal rules of the world they live in, so they are still perceived as unequals. The tension and drama, that enhances the romance, is how Miina acts in regarding to these rules, and whether she chooses to live as an equal or as a robot.
