This is such a cute series, I'm glad it came back so I could discover it :) the author seems to be making up for her haitus by including much more physical affection than was previously in the series before the break. These gay sisters and their gay friends are all precious.
I'd almost managed to forget about these cursed things, which are apparently a Costco Japan exclusive. I have read several posts and even seen a couple videos about them, and nobody seems to know why they exist. I wonder if Costco in Japan got started after Japanese people got experience with it in Hawaii…
