Where can I find their friendship level?
As I said, "Simply click the info tab and tell us the number next to her name."
Where do you see "Friendship Level"?The only mention of that should be "Relationship Level".
Those are the same thing.
I think they mean when the game tells you to "increase friendship" with one character to continue with another's events, and didn't realize that means progressing further with the required character (which would raise relationship/friendship level)
