Thanks for the scanlations :D
I can't get enough of these two. Them not holding onto the raincoat and completely forgetting about the wind causes Ayumu to get soaked, but Ayumu just doesn't care because she's so happy. They're so adorably stupid.
Also, this is the second time Hayami and Ayumu talked about Saturn's rings! Hayami completely forgot everything from
the first time already. She just wants to run on those rings... Ayumu also seems to have forgotten, probably because she's so excited to talk about Saturn.
I wonder if Saturn's rings will be a recurring topic, each time leading to different developments.
