I found a small bug in Kendra's sequence. I will quote event numbers from the v0.33 walkthrough for reference.
After step 642, don't do to your room and go straight to the hospital at 14:00. Go to Kendra, complain about the pain, and in the hospital room just go to sleep. MC will have the talk and will apologize to Kendra in the morning and raise her points, even though the BDSM event has not occurred.
I mentioned earlier that while playing what I learned later to be a bugged version, my char had 105 energy points. Now thanks to Kendra, MC's energy is at 115. I heard it should be only at 95 now though.
