"Instruct the child of a good family in various academic subjects." ~ Cube
Olive takes time to help the countess' son in his studies. This helps her learn moral lessons of her own and become a better person, but it's taxing to tutor someone for long.The long stays also take a toll on her appearance over time.
There are few upsides to this job. It's quite stressful and it doesn't raise morality any better than church work. The Charisma drain is a problem as having decent Charisma influences quite a few things by age 14, such as working efficiently in its rival job for one. While the pay is good, it's not much higher than some jobs and salon work has the same base pay at age 11 while being significantly less stressful and draining a less important stat.
What it's useful for is getting a few endings where Morality is greater than Faith. Even for that situation, it's probably more efficient to just use science classes for draining faith and combine it with church work, unless you don't have the money. Lastly, this is the only other job that raises maternal instinct, but it's usually better just to use babysitting early on to raise it.
