That was a thing for both karaoke and video rental when I lived in Korea in the nineties.

The karaoke was more a place to go with a group of friends and the video place was more to go for a private place to grope your girlfriend while you watched the latest Tom Hanks movie. Think going to blockbuster, but then they immediately put the movie on in a private room for you.

Sometimes in the summer, I’d go rent a video room by myself so I could take a nap in a dark air conditioned space.

Edit: Maybe I used a phrase that was distasteful, but I am not relenting from stating facts. Here’s a description from an online article about Korean “bang” culture. Bang means room in Korean

One of the first modern bangs to emerge in the late ’80s was the video bang, which provided a place for people to watch movies on a large screen with more choice than the cinema’s limited releases. They also fast became a popular place for couples, thanks to their privacy.
