Thank you for remembering! Yes, when Hotaru sees cherry blossoms, she becomes sad because she remembers her friend who passed away. That friend crumbled and disappeared just like the cherry blossoms. Actually, she hadn't decided what season he died, but she did decide that she met him on a rainy day. The rainiest season in Japan is June, so she probably died around July.
I was going to ask you why Hotaru looks sad, but I remembered her
background story, it’s because of her friend right? the other Hotaru..
it happened around this time?
