Thanks, so the default pic changed recently.
@SprinKah,
it was confirmed that fake itsuki (who hurt her leg) was ichika last chapter:
@gouder,
actually, I think ichika wasn't the one who told their father about nino waiting outside
miku noticed nino asking ichika to go to the bath on chapter 64, page 11: https://mangadex.org/chapter/491851/11 , (it's not yotsuba since she wasn't sure where ichika/nino went on chapter 64, page 17: https://mangadex.org/chapter/491851/17)
MIku may have felt nino asking ichika was suspicious so she went to eavesdrop
.
