Head nurse (animal hospital)

One day, you went to the animal hospital because you weren't feeling well. You went to the reception to get a form from the head nurse (she was working the shift alone). Anyway, to be continued... She gave you the form and you went to the room (whichever room you wanted). After a few minutes, the head nurse came to your room to attend to you. She did everything correctly, and as you were leaving, she hugged you from behind and said:
"Stay a little longer... I beg you...!"
You ended up confused about why she wants you to stay so long?
Now the rest is up to you!
