"Zoe it's me! Listen I..." you wanted to have the initiative, let her know that you did this just for her, that you would do anything for the privilege of being her boyfriend once again, but there was a slight problem.
The person you were looking up at wasn't Zoe, even if she had a couple of similar features. It was her mother Kate, a situation that you didn't expect even if it shouldn't be that surprising. Maybe Lydia just put the address in the package and didn't mention you were a delivery for Zoe's eyes only, maybe her mother got suspicious enough of a strange box coming with her usual mail.
"Wh..what are.. you?" She sounded scared. You could understand her, you considered her a sweet woman that wouldn't harm a fly but also wouldn't be fit for some of life's thrills like seeing a tiny human being delivered to her house. She probably considered this impossible until she saw you, and to be fair to her, so did you until stumbling into that dark web page after the umpteenth attempt to find something that wasn't fanfiction or a scam.
"Hey Ms. Kate.. It's Jack! Could you take me to Zoe's room?" You tried to not be awkward and utterly failed, you just were completely unprepared for this. You scratched your head and forced a smile tried to appear laid back about all this, but your legs were shaking a bit and your voice trembled when you greeted your ex-girlfriend's mom. Not only because you weren't that close to her, but also because you didn't know what she could think about all this. She was supportive of your relationship with her daughter, but since the last time you talked was before the affair and break up you didn't know if she actually liked you or not. It wasn't hard to guess she would be on her daughter's side but you at least hoped she could get you to Zoe. That was all that mattered at the moment.
"J-Jack..How di..." The surprises continued as she suddenly moved away from your box and your cardboard environment got violently thrown for a second. You felt as if you were in a high speed car crash where you couldn't control anything about where your body was going to land, and fortunately enough you landed on something so soft the only thing you had to take care after was your dizziness.
"What did just.. Ms Kate!" Once you recovered you looked around and noticed you were free from the box, laying on Kate's bed with the envelopes of the rest of her mail. You also saw her motionless body laying on the bed in a kinda awkward position but still breathing. You couldn't believe it, she actually fainted from seeing you! The poor woman..
You wondered if there was any way to help her, but at your size it wouldn't be easy. Maybe you should just go back to the box and attempt to explain things to her once she recovered? But then you remembered the main goal was Zoe and wondered if you should go to her room instead, it would probably be for the best as she could help her mother in a better way that your shrunken self could.
What happens next?
