I usually don't like Established Relationships. The appeal of romance to me is watching people fall in love.
This is an exception. It's sweet but for some reason it still aches. These two people who grew from childhood into adulthood together. Love incredibly familiar but they still need to communicate. They're just average joe's who adore the fuck out of each other and this is like a glimpse through their eyes at the other person. It's dorky and silly and beautiful.
