This is the video in question (Read the description FIRST, it makes the video 10 times creepier and is also the basis of this theory): [link]

 It's a damn shame this video isn't more popular, oh well. Trigger warning for implied abuse and rape.

 I find the entire story very interesting; this perfect woman apparently made by a modern Pygmalion and why should WE judge her based solely on us finding her creepy when another finds her beautiful? When he loves her so much and she feels so FANTASTIC?

 However, when listened to closer, the song has some disturbing moments.

 From 40 seconds onward she says 'I feel fantastic! Hey, hey, hey! Run, run, run run...' and looks down, almost sadly, when she says it. Trouble in paradise?

 We don't know who made her, and we can only assume it's for similar reasons to the Pygmalion story as that's what we were provided with. It must have been quite a project, as it is implied she is, in fact, sentient and able to think and feel. Otherwise, I doubt the creator would put a line into his beloved's song that could possibly imply abuse.

 I also highly doubt it's just because she likes running, She looks like an average stay-at-home wife, and according to the description, I think that's what she was made to be. This Pygmalion fellow songs kinda sexist, having no respect for woman and trying to create a 'perfect' one.

 She's singing an ENTIRE song about how she feels fantastic, then out of the blue 'Run, run, run, run...'

  The song goes on to sound vaguely like 'please me, please me' over and over and looks away from the camera. She may be parroting her creator forcing himself upon her. She then exclaims 'You are FANTASTIC' which may be what her creator said to her after, or what he says to get her to like him. She then again says 'run, run, run, run.'

 It says in the description he may feel her as being the perfect human or a Goddess.

 That sounds like obsession. We ALL know that never turns out good.

 Yet most of the comments are of how creepy SHE is, when there is all this juicy subtext...It's not even that popular of a creepypasta video, it's a pity.
