If STR less than 100 choose to "Save her" for H Scene = BAD ENDING

Reload back into the Day 27 save, go on the rooftop and interact with the plant. This time select the option "I read in a book". Then go over to Douchebag's apartment and interact with the water dispenser. Progress through Day 30 and save the Neighbor on the rooftop with at least 100 STR or more for the TRUE ENDING.
