Somehow this manga brings some of Strawberry Panic aura. 
But better: Like  Shiritsu Ririan Jogakuen in Marimite, St. Miator Girl's Academy (the school of the main characters) is purely for making its high-status girl students into desirable brides, and keeping them away from men until then. Hence all the despairing lesbians.
The other two schools are more diverse, though still with a marriage emphasis.
But yeah, the relationship stuff may be similar.
How do they keep the species going? Send out to Saki for science babies?
