The 3 Steps Plan is a darlingkeeping and family planning philosophy proposed by Strathamian priest Mars Altair in 1941. He believed that the ideal Strathamian relationship progressed in 3 phases, based on age brackets. Though modern clergy often criticize it for being ageist, the cat is already out of the bag, and even teenage yanderes in Stratham aim to follow it if only loosely.
Stage 1 (18-24): Marriage and training, preparation for parenthood. The yandere must make sure that not only is their darling obedient, but that they are both mature enough, knowledgeable enough and healthy enough to produce heirs. They also must make sure their home can accommodate a family.
Stage 2 (25-43): Procreation and raising children. The most important stage, as Stratham’s religion focuses heavily on having many children.
Stage 3 (43-???): With children grown and gone, the darling will continue with their prescribed duties. The most relaxed stage, according to couples surveyed, and understandably so.
