Between windows and windows

prolog

I have a boyfriend who I've grown up with since I was really young.

Our two mothers, who were high school classmates and best friends before we were born, said they had dreamed of living right next door to each other since their school days.

So, they got married around the same time, bought houses right next door to each other, and had us around the same time, so we had no choice but to hang out together every day.

What I hate most is that the window in my room and the window in his room are just an arm's length away.

It's so annoying....
