My crush found my secret notebook (I mentioned him there) and it's likely he read it all right?

We've already known each other since 5th grade. At the time, I didn't know how to express myself too much so instead of showing kindness towards him and a couple classmates, it was the opposite. However, I would target him the most.

Eventually I started outgrowing that stage and we (as HS sophomores) get along fine by now but my long crush on him remained a secret. Then just last week I accidentally left my notebook.

The next day he returned it back. He said he found it and was like ''thanks goodness I found it. People nowadays steal things. You got to be careful with your personal items''. Yet there is one problem. In order for someone to know it's me, someone would have to see my full name written first page. It isn't just my name written by also a picture of him from our school yearbook and me basically confessing to always wanting him since we met, wishing we were together and more things.

If the only way for him to know it belongs to me is to read my name on it and by reading my name, he would be reading everything I just wrote and see his picture. So now he knows and likely read it all right?

There is only a slim chance he knew it was my notebook, maybe by just seeing the color (it's black covered composition notebook) but unlikely. Like mentioned my name isn't on the cover but on the first page.
