This isn't "another option". This is an option that should have been there to begin with.
I can't tell if some of you guys just like to exaggerate or if my post isn't clear enough. Asking to share a personal house with at least one other person is not an outrageous demand, especially in a game that is not only adding a marriage system, but is facing the problem of not having enough houses.
People share houses by their choice=less houses are needed.
