[romance]

Ok, now my subjective interpretation...
Ayu walking with key through the corridor with her doggie - represents Ayu at the moment.
Locked doors - Ayu's unknown future
Notice, please, the other doors are unlocked, so it may mean (according to locked future) behind them there's something from the past. Ayu opens the doors and what does she see? Herself, but she's a watcher this time, so it's a chance for her to get the outside view for her career. It scares Ayu, that she looks like that for other people (I mean, as a dictator and so on). We can see she's terrified, she's running away, but then she meet present Ayu = herself, and understands she's noticed as a girl without personality (with no face).
The last scene = on the bed. I cannot understand it. But it reminds me all that scary horrors. I remember Ayu face, her 'empty' sight. Light -no light - light = Ayu's playing with person watching pv, and the way it is scares me. I dunno, I link it only with sentence "You cannot hide, there's no shelter". But I can't figure out why -.- Oh, crapy interpretationX_x
