If the author wanted a real twist, the duo should come back and discover that somehow Shiori (glasses wingwoman) has unintentionally gotten closer to Niijima.
Well, this light-hearted chapter would be nicer if we didn't know about her current home situation. It's amusing how quickly Takae sniffed out their intentions, though.
@boag Until the situation with her mother is taken care of, I don't think we can rest easy at all. The references to the story about the guy losing his memories about his past after reincarnating is very worrying as well.
@Tersione I don't really think the reincarnation without memory part was foreshadowing as much as much as a contrast to their situation, where everyone thinks the lack of memories is an ironic misfortune, while being faced with the situation in reality presents a lot of potential problems and sources of suffering.
@Dombl Very interesting interpretation, especially if seen as a counterpart to their situation. But given the slight darker undertones of the story, I wouldn't dismiss the amnesia thing entirely.
