Heeey ~

So, I need help remembering a yaoi manga. It was a collection of short stories who all were generally pretty dark and twisted. One of the stories was of a young boy in shool who believed he saw aliens and ufos and that they were doing things to him. But it was actually his coping mechanism for what was really happening in reality, which was that he was sexually harrassed and eventually raped by his teacher.

EDIT* I also remember the boy had a friend (his age) who had a crush on him. The friend misunderstood and thought the boy had some relationship with the teacher, and got super jealous.
