wait did you get the 'forever alone' ending?
I did these options though
1st meeting
"hi"
"comment on how interesting the play is"
2nd meeting
"compliment Barnaby's notes"
3rd meeting (at 06:00 pm go to library to work on your class project with Barnaby)
"Disagree"
4th meeting(at 06:00 pm go to library to work on your class project with Barnaby)
"go to the door"
that's all I've tried talking to him and he avoids me, but at the end I've got his ending.
"Barnaby Fail: Breaking Barnabad", You'll get the 1st CG in his student spellbook in this ending, but this is if you're asking about his fail ending
