Guess I never gave my opinion on the grind but I have use the PC Console for version 1.6-1.9 Expansion.
V.2.0^ Stats system addition replace the level & Exp grind for the Guardians this is what made me play this on Android port without the mods. In a single day you can grind 10K Good Master, Knowledge, Speech, Strength. 3 of these stats can be max through the Breakfast options Shower, Workout(loop), to get to school choose Coffee option. You can now get 10K knowledge Study in MC Room during Time Lock another feature that's new & probably still in test phase for something else, and can be activated Friday Evening by accepting shopping w/Sophie from the Kitchen & can disable by starving or Elisa Bed Rest or w/Slaves. You can use Time Lock to gain Food by sleeping on Korosu Island. You can also unlock Infinite Car Energy by leaving Cave of Oblivion through Bed shortcut then with 40 Energy Enter Rosa Blanca Palace then leave the Palace to see 0 Energy, then go to Beach to see -40 Energy that's it. As for Fame starting Jennifer Mission 1 & completing it 7 times a day along with spawning Special Gym Clients like 50 & 60 can get you 110 Fame the trick is timing of the save before bell sound & reloading game cycle Clients thumbnail just reload on Denise and save for the second time. Do this then within 10 days you will get over 4500 Fame, only need it to upgrade Silver card & Gold Card to unlock endgame content when the Resort fully open it make 640 Fame per day. The Grind is way shorter then before so the Stat system is a great addition that lessen the grind, now i just need to wait one more update to see Party system. Seems like it was missing in V.2.1 Part A for Sasha Endgame content.
Most important stat now is Knowledge for Maids & spending 500 Knowledge on the Maid for 1 point E.ATK Stat will make attack miss less or kill in one hit like at 105 E.ATK- Sophie can cut down 8K Hp using MP Attacks or regular if higher stat.
Red is currently using the Maids default system only as a Placeholder, since she is a Hunter without Aura to link with the MC plus she need to remain sane & blessed to stay in the cemetery, so the upcoming Craftwomen & Blacksmith system sounds like something from a RPG game.
