I still need to pick up the novel, but
I'm really left wondering when Sendai will finally come clean about her circumstances in full, and why she's doing all this with Miyagi (i.e. to fill the emptiness she feels, and to give her a place where she can be herself and not have to put up a front like at school/around her friend group).
Miyagi's playing cards close to her chest as well, but they've been dancing around one another for awhile now, both too proud to "cave first", as it were. The transactional nature of their relationship is being almost forced, rather than merely enforced, and it's only a matter of time before things break, given how they're both starting to push the boundaries of "what is agreed upon" between them.
A bit of openness and trust feels like it would both solve problems between them, but also offer a path of growth and progression that could see other core issues resolved, or at least tended to.
But I don't believe we're at that point, just yet. Stuff's gonna have to just nearly break, before things will actually spill forth and true bonds start to form.
But, thank you for the TL work as always.
