The Disastrous Love of Saiki K! (Yandere Kusuo Saiki x Reader)

(YN) and Saiki have known each other since they were very young. (YN) was the first person to ever make Saiki feel like a normal boy. Later on in life Saiki realised that he couldn't live even a day without (YN), and thus this is the story of Saiki and (YN) obsession filled love story. I do not own any of the characters from 'The Disastrous Life of Saiki K' This story is following the episodes of the anime and most of them will be through Saikis Pov.
