@bluedudu its pretty obvious the tower was some godly artifact (how else would the glasses be in working condition after all that time), clearly whoever ventured in there would find exactly the kind of item to grant their wish (like if other girl hadn't wished for a friend/companionship, she would probably have found some sci-fi healing station that can even restore lost limbs). Particularly as the ad said they would fulfill any wish, which is something no mall can possibly claim, its probably that deity's message.
tl;dr - Too much of a coincidence. The god myth about the tower must have been true in-universe (although doesnt have to be a god. Any kind of seemingly omnipotent being works).
edit: another thing to note was how there was a mention of some being appearing at moment of birth, genetically enhancing ppl.
