Mingyu just turned 20 and his life is already a big mess. His parents didn't want him to be with them. He was kicked out of the house at 19 years old and lived on the second floor of a bookstore ever since. Luckily the owner of that store, Vernon, became a good friend of his. After finishing high school, he couldn't find any colleges that would take him. Vernon wanted to introduce Mingyu to his little gang, which contained Vernon, Seungcheol and Wonwoo. But there was one little problem. Mingyu fell in love with Wonwoo, but he knew it would never happen. He did find a job as assistent, but his boss is really aggressive. Mingyu tried to hide it, but he couldn't.
