In the song 「ケロッとマーチ！」, there is the following line that confused me a bit:
I interpreted this line as meaning: “Ah, the train station was 5 minutes away, not 15, like we thought!” However, you’ll notice that the は particle appears twice in this phrase. Am I mistaken that it’s only supposed to come once in a sentence, or can it only be used once for the same purpose? Is it just a stylistic choice?
Here is a link to the song, if it makes any difference (the line is towards the end): https://youtu.be/llp-Gm8llVA
