Ok, somebody help here.
Assuming that blonde at the end is Kaoru, that means she, fully aware of Uta’s feelings, is still living with her, and Uta has now accepted she’s doomed to never being loved back (at least I didn’t see any love there), which is super uplifting.
Assuming she isn’t Kaoru, that means Uta is going out with someone that looks like her to cope with her rejection, which would be just awesome.
What exactly did we accomplish again? Or did I misinterpret something?
