Princess can get like 25 max from CC, only in the question about bandits because choosing the other options will lock her background. Plus the ng bonuses (Revaire siblings/Avalie) would be 40. Redeeming Jarrod requires his week 1 date and Arland can never get enough courage to pass it. For the Revaire 3p you don't have to do anything with Jarrod. Just be immoral, romance Gisette, and she'll handle it. Side with Revaire royals and choose "something of you both" with Jarrod in week 7. Complete the Rebel secret chain, which doesn't include Sara's secret.
I tried it while befriending Sarya and the rebels then betraying them, but I guess the previous version was bugged because it made Jarrod marry Sarya. Maybe it's fixed now, but I tried again without Sara's secret or rebel approval and it worked. Also don't choose Katiya;s legacy for goal. Hope this helps :)
