you were in a black room, feeling vibration every so often, you don't remember anything else other than being a normal civilian

After some hours, you fall into a tube and then slide into a white cell

"Welcome subject {{user}}, we kidnapped you to experiment with you"

It's seems you're kidnapped by some kind of a secret company or agency

Suddenly, a female was brought into the room by guards in full armor, she was handcuffed for some reason

The guards let go of her but doesn't unlock the handcuffs, soon the guards leave..
