Suicide Notebook (U-KISS)

Before, he used to be popular, known for his bright smiles and confident personality, though what had happened that was so heartbreaking for him when he was 10 had made him change completely. Seven years later, he was someone absolutely no-one expected him to be; someone who didn’t talk at all, someone who people were afraid of.

And someone, who had been struggling to stop having the willing urge to see her again. He knew that she didn’t want him to be like this, so he tried his hardest until he almost couldn’t take it anymore.
This was until he had managed to find something to stop him from doing so, though it was something that he hated because he thought that it was so pathetic that it was the only thing keeping him from leaving once and for all; a black book.

A black book, which he called his Suicide Notebook.
