Rumi.. is..
I'm still pretty confused about Rumi's role in all this. I was pretty certain she was real but how did Mima manage to dream up the photographers murder? Is it meant to be a coincidence? Otherwise the only explanation is Rumi is imaginary (would also explain why Mima couldn't recognise Rumi when she dressed as Mima). Then the ending got me thinking that maybe she saved what was protecting her innocent idol phase (considering it was all in her head) so it would never disappear for good (like the psychiatrist says).
Do not speak- unless it improves on silence.
