yeah, that would probably be it.
but for me, " i hate you from the bottom of my heart" sounds friendlier than "i hate you from the bottom of the earth"
if my translation sounds strange, i'm gonna change it
i was hella confused too
The "Do you consider yourself a guardian" & "What are you, a guardian?!" is 保護って言いましょう? ( Hogo tte iimashou? )
i don't know what fits better, so i just put both of 'em there
i'm still learning japanese, there might some errors in translations
