Black Day (South Korea)

Black Day is a special day that is celebrated in South Korea on April 14th. It is a day for people who do not have a boyfriend or a girlfriend, and who feel lonely and sad because of it. It is a chance for them to get together with their friends who are also single and celebrate being single!

The reason why it is called Black Day is because people wear black clothes and eat a special meal that is black too! The meal is called 'Jajangmyeon', which is a type of Korean noodle dish. It is made with black bean sauce which is why it is so dark!

On Black Day, people usually go out to eat Jajangmyeon with their friends who are also single. They might also go to the cinema or play games together. It is a day to have fun and not worry about being alone.

Overall, Black Day is a special day in South Korea for single people to come together and have fun!
