1! where do I start. . .

A boy named Mayumi is abandoned by his parents because of his schizophrenia and autism. Living alone in the streets not knowing what is true or false, what is real or fake, he struggles to do anything to live. After causing some trouble, he was sent to a mental hospital.
On one faithful day, he met a beautiful girl with purple hair and six pointed star eyes after he saved her from murder.

"Are you real? Or just another hallucination."

I do not own the characters from Oshi no ko or the anime/manga and this story's protagonist and the story is completely original.
