^ Well, not exactly. Instead of having another crease on top of her second one, he fixes the existing second crease and raises it up a bit so it's not likely to collapse under the first, natural crease of the eye.
I've seen it done actually, but yes, Ayu's many folds are a result of the glue/tape. Before she started using glue and her second eyelid was smooth (aka multi-creaseless), that's what I
believe she had done. The world may never know, and we could probably keep debating this til the cows come home XD;
