Damn even with trying to optimize my 2nd playthrough with the hint mod (which sometimes does weird stuff like not telling me i needed lust requirements for certain timed events, but then telling me about other ones) it's crazy how often i end up completing the last available event on like... a saturday, and then the next one is on... a saturday.
Also, in terms of things being worse if Sensei doesn't fuck everyone - not banging the married magister of mammaries so far seems to have a better effect on Haruko, at least so far...? It's possible she snaps later on, but so far she seems happy just having a normal friend.
