If I unadd someone on snap, will they know?

Like will they still be able to see my stories and stuff?

I thought I heard that if you unadd someone then ur story will start showing up in their subscriptions or something?

Also last question, if I unadd someone, is it like , I’m not friends with them on snap but they are friends with my still or is it if I unadded them on snap so now we both aren’t friends on snap ?

Sorry if that’s confusing
