Jungkook was a 19 years old introvert boy who didn't have any friends and liked to isolate himself in his room most of the time until he discovered a new messaging website called Red String for lonely people who are in need for someone to talk to from all across south Korea. He decided to give it a shot hoping it will help him get free of his loneliness and maybe make some friendships not realizing that it will lead him to meet the love of his life.
