I still don't get Itsuki, dhe likes Fuutaro too, doesn't she? or is she just trying to help one of her sisters? I think we all can agree, Yotsuba was "childhood friend" candidate since almost the biginning, but Itsuki...
Miku is my favorite but Yotsuba is so relatable.
Good chapter to expand the plot.
By the way. Is it just me or Itsuki dressing up as "Rena" (Yotsuba) makes no sense. I mean what's her goal?
