Viewing post in Version 1.5.0 - The Miss Esther Update comments
This is not a bug. Miss Esther's ending has 3 specific requirements:
[SPOILERS]
- You've unlocked both of her cutscenes
- You've earned 10 or more affection points with her
- You were confessed to, but turned them down (on the track to getting the ace ending)
Have all 3 at once and you'll get the ending.
This ending is perfectly reachable, multiple people have done it. I appreciate the report but this is not a bug!
