i feel like there's a chance that the older sister left machino on read because she might be taking care of one of the other heroines. is that just me? am i crazy for that, i don't know if i'm over-analyzing what i'm seeing here because i want more chapters and am stuck with rereading what we have right now. but if they were close and are still on speaking terms now then it feels a little weird for her to leave her on read and not even text a reason or an apology for her being too busy to talk.
My earlier worry is still kinda sitting in the back of my head, namely that we had an entire volume to get to know Sofia but Olivia is already departing after only a couple focus chapters. I guess it can't be helped that Olivia is feeling cucked (how harsh for her to hear Machino mumble Sofia's name in her sleep instead of being relieved for her arrival!) and doesn't wanna stick around though.
"a couple" is right- olivia has only been here for 2 chapters (plus technically the tail end of the chapter before her introduction proper) compared to sofia's 6. there's also that promise that olivia mentioned in her monologue that was not expanded upon at all. olivia is definitely backing off because she's hurt, but i doubt we're actually dropping her now.
