Hi,
Be Fine isn't very popular in The Sims 4 and Be Happy includes too many moodlets.
Fine emotion could be the opposite of the Uncomfortable/Anger emotions. For example a well decorated room could contribute to it.
The sims could even feel "Very well" or "Be Soothed/Feel Calm".
While the happy emotion should instead focus on tasks that allow sims to enjoy life.
This would show best when Sims are actually having fun instead of being happy all the time without doing anything in particular.
