Spoiler for End of Kanata's route:

The only conclusion I can make with this scene is that this is the aftermath of yet another loop for Kanata, representing what Haruka meant that they will be together over and over again.
And considering their memories from previous routes are kept intact to a certain extent, there isn't really any more grief between the twins, although the Saigusa is still a pain, so the LB'd wait for the wedding ceremony to barge in and save the day.

With everything witness so far, I feel even more annoyed that

Spoiler for refrain, true route:

Refrain didn't state clearly what happened to every girls in reality: whereas heroines like Yuiko don't need really any "real life" conclusion (considering their problems had happened and they went ahead with that), other heroines like the twins, Aya and Kudo might need more clarification to what happened to them/stuff related to them... well save probably Aya, considering the "obvious" consequence...
