100% agree. I noticed early on that Subaru would blush during some interactions with Fuuka, especially when Fuuka patted her head. I definitely interpret their last interaction alluded to their potential future together.
Poor Hana! She's got new friends that are much nicer (though Sadako is a murderer lol). I can't wait to see the drama between Hana and Sadako stemming from Sadako's past as an Oni. The pacing of the last chapter was a bit funky so I'm glad to see the its reverted back to normal.
