Mixed feelings about this chapter.
I like that Yotsuba is finally getting focus and that Fuu & Itsuki still has a very interesting relationship. However, the resolution to the conflict between Miku and Ichika is really underwhelming. All that rising action towards the climax of this "Sister's War" arc feels fake now. All of Ichika's deception and Miku feeling sorry for herself... all of it now feels like a cheap plot device to create expectations for the readers and then "surprise" them with a "shortcut" solution.
Ichika is able to develop, but there are no lasting negative consequences to her actions. Her sisters still trust her just from her actions last chapter despite her many previous deceptions, and Fuu still respects and cares for her. I AM NOT SAYING HE SHOULD JUST DESPISE Ichika but the execution to why he feels that way needs more context. AND NO ICHIKA IS FAR NOT OUT AS A POTENTIAL BRIDE TO FUU.
For Miku, she just made feelings ambiguous really. Basically, just like before this Kyoto trip. Fuu already suspects that she has feelings for him since the end of the Scrambled Eggs arc, which is further confirmed by the events on top of the hill, his conversation in the bus with Yotsuba, and Miku's reactions prior to her confession, but she just makes her feelings ambiguous in a form of a tease. SO HER POSITION IS REALLY NO DIFFERENT TO NINO... they are in the WAITLIST. Only that Nino's confession is non-ambiguous, and Miku's is ambiguous. Ambiguity normally results in misunderstandings and frustration soo... yeah.
