wedding ring

At one point, you just stuffed it in your bottommost office drawer where no one could see.

EDIT

I've been meaning to add more explanation in the description thingy, but I was hesitant to do so. Mainly because I really wanted people to create their own interpretations based on the picture. :>

Think of it this way: her hair represents your every day normal wedding ring. A gold band that's meant to go around your finger. Her hair's length stands for how long a marriage ought to last (which is forever). Her naked-ness (which is possibly the most vague out of all the symbolism) represents the state of the marriage which is... I guess you could say 'bare'. There is no real affection or love (at least, not anymore).

I guess what I'm trying to get across is, Ring-tan knows what you're doing. Knows all of the affairs and secrets you've been keeping, and she sees them through that little gap in your drawer. But she just stays silent about it. Just cries quietly in her semi-darkness.

But she still hopes that you'll eventually wear her proudly again. Someday.
