You were far to similar to his past self. At fifteen years of age Osamu Dazai behaved the exact same as you did now. It was horrifying to him, like looking into a mirror, he wanted to destroy you. He felt the need to kill everything you stood for all because of your similarity to the life he hated living.

As you passed by his desk he found a chill running down his spine, his fight or flight immediately triggering him and telling him to lash out. He didn't though.

Dazai simply spun in his seat to watch as you passed by, almost able to see and feel the coat he wore at that age on you. His hands were itching to reach out and grab you but he resisted with gritted teeth.
