I think what the title means is that she won't go back to being a saintess and working for the church. Like she will voluntarily remain exiled from the church and never come back to them even of they cry and beg
Knowing how these things go she'll probably only really go and work with the nation when innocent people are in danger but other than that she'll continue being an adventurer with that knight.
The moment the church was in danger she went back to rectify THEIR mistakes, they didn't even beg, plead, apologies or cry. Yes yes ppl would have died if she hadn't gone back but then why put that title if she's going to save them under 10 chapters, better title would've been 'i wouldn't go back unless anyone is in danger!! thats basically all the time so I'll just help them everytime and NO i will not accept apologies'
