A Blind Date Tomorrow, a Knock on Your Window Tonight – intro video

You've been working overseas for two years, and this Chuseok is your first time back home in Ssangmun-dong. Your window and the second-floor window above the laundry across the way are separated by nothing but a narrow alley, close enough to touch. As kids, you passed notes, tossed snacks, and fought across that gap. In the middle of the night, someone knocks on that window again. She leans out and tells you her mom has set her up on a blind date tomorrow. Then she asks if you still remember the promise.
