Many people with 1 year working experience will encounter such problems, and there is really nothing to write on such a resume.

You can usually write like this:

First: the work content and responsibilities of these months (maybe very few, but write it down)

Second: What did you realize or understand in your work (important, because you have little else, you can write more about this. Work and school will definitely give you different feelings and positive aspects)

Third: the reason for leaving (just write about your current situation, no job ...)

This mode will be OK when it comes out.
