The で here confuses me, here is what I think the translation is and I'm not sure if mine is even correct.
When everyone from the same region grew up from elementary school, (Then the 2nd で confuses me)
I think the 2nd で serves as the location particle
When everyone from the same region grew up from elementary school, in the school year I was the only one who moved from Shibuya to transfer to a school.
I'm pretty much confused on how the particles are used.
