This short manga has a story to tell and it does so excellently.

The concept is creepy in a fun way, exploring the idea of obsession and our own inability to control ourselves in the face of something we wish we could have.

It reads almost like a classic SCP or CreepyPasta, giving you just enough to get you thinking and then leaving you to figure out the rest for yourself.

I wouldn't call it a mystery or even deep but it's a fun idea to think about in your day dreams or to incorporate into your own writing projects.
