MUST READ THIS!
So, clearly this will be a G!Sans x reader. But, don't think you will be with him straight away, and that he is going to fall in love when he first see's you.
Now, you are going to experience a lot. I am in control of your actions, your words, the way you dress and your age.
This most likely will be a slow-burner.
OC'S will be used. Don't like it then don't bother reading this.
OH! Nearly forgot, this is not going to be a smooth journey for you.
