This took me way longer than I thought it would and I'm not entirely certain as to why. I had some writing indecision, which is easily understood, but the drawing took me much longer than I expected.
I was originally imagining they'd wind up in matching one piece swimsuits, but thought that was a little weird given that Nanase was already in a swimsuit, but I also wanted something a bit more covering, so we wound up with these.
In retrospect, there's probably not an option that isn't weird.
