"Please release him!" you said, but what do you want him to be released from?

"Please release him!" As I was about to return to the classroom with my friends, I was suddenly stopped by a young lady I didn't know. "Who are you?" Why does she seem surprised every time I ask a question? It's as if she's saying, "What?! You don't know who I am?!" but I simply don't know her. Apparently, 'he' refers to my fiancé. She said to "release" him, but from what I can see, he doesn't appear to be confined by anything? ※ A fictional world based on medieval Europe ※ Plot convenience applies. ※ I correct typos, omissions, and awkward passages as I notice them.
