Single post in A Beginner's Guide to Happiness and Fields.

I´m trying to evolve two of my eevees into Sylveons, and it says both their Happiness is Max, but they still can only evolve in Espeons? I gave my male eevee I´m trying to evolve 2 perfect Cheri berries, cause he likes spicy food. Am I doing something wrong? I can´t find any actual numbers for their happinesses.
