Great chapter.  Maybe I'm unimaginative but I like the chapters of plain Riko and Haru interaction the best.  Also wow, Riko's personality is really sweet.  The mom situation/stuff is pretty important for establishing her character, I wonder if we'll get to see her show up at some point as well.  I feel like the story has set up a good basis for itself at this point, will be curious to see where it goes next.
Thanks to the YP team for the chapter!
