it's an idiomatic expression which means : you are making an agreement with someone not to be angry or bitter about something that you probably fucked up with.
I fucked your Girlfriend, sorry dude, but if it makes you feel any better, she sucks in bed, so no hard feelings ??!

Hard feelings means sadness or taking stuff personally, or in a hard harsh way.. you can use hard feelings like, “no offense” or “not taken personally” or “no hate”
