I don't think I can do anything for now, no matter what your choice is, but if there's a way to avoid this, can someone tell me or is that what we have so far, after all, how far does the game's story go?
If you still want to change the story You should choose to tell truth to priest bot (option above). Once passed, there will be no more scenes where the bots(jun) disappear. (Google translate not 100% sorry)
Go to 'iamacheater' in your browser and click 'reset church storyline' and like MrNewoo said when you run into the interaction with FF be honest about Shanice's concerns about him.
