OMG I'M SO happy! I didn't think this would get attention so soon i'm so thankful >///o///<

And no it's fine! They had the most interaction probably I think in Middle School, but I'm happy with Kags in either middleschool (Kitagawa Daichi) or HS (Karasuno). You are free to even explore this starting from middleschool and towards HS (Kags in Middle School and Iwa in HS like you mentioned)

Thank you so much for being interested!
