http://auideas.tumblr.com/ prompt found here! I used the "Home is where I am with you" AU. When Character A's spouse files for a divorce, they suddenly find themselves struggling to keep their family of three financially afloat as a single parent. It's not long before Character A has to move to smaller, more affordable housing, which is where they meet their neighbor, Character B, who is also single parent. Soon, Character A's kids start referring to Character B as their "other parent," and their kid(s) as their "sibling(s)." As Character A and Character B's kids grow closer, so do they. Between picking the three kids up from school, to taking the other's child to ballet/soccer/sports practice, something like romance begins to form.
