They didn't splits cours, so I also wonder if there's a second season planned.
I'd have to check but there's an angle to the story in the first ep and another one I don't remember we had in the first run. Short scenes but that might point to the will to complete the story.
I did not check any anime source. My guess is that we will know at the end of the summer season and I'll update if last summer ep tells about a continuation.
