As always thank you so much for your work !! This manga, themes and characters are always so touching and powerful i love it !! The waves analogy and powerful connection between generations is constantly striking a chord with me !
Also i found the movie poster this time ! Its "A Beautiful Day in the Neighborhood" (2019) by Marielle Heller (I haven't seen it so can't really comment, only know its a biopic about an old tv host, but I believe its about the connections we make as humans and between generations also maybe ?)
