I use Kakao Talk and YouTube the most. Until two years ago, I spent most of my free time enjoying Instagram. At that time, however, a new content feature called Reels was launched, which made it hard for me to control my overall screen time. It consists of short and stimulating video clips. Because of that, I decided to delete the application. Although removing the app caused me to feel disconnected from society and bored in the beginning, I eventually felt more free. After the experience, I often use Kakao Talk and YouTube instead. The former is the most renowned messenger in Korea, and the latter popular is the most well-known video platform in the world.
