Here we have a different story. It seems each episode will be a standalone story rather than a continuous one, at least regarding the letters delivered by Fumika. This episode is about moving forward, letting go, and forgiving, but it’s so hard when it comes to parents—in this case, a mother—so I totally get why the daughter didn't want to read the letter at first. I liked the ending! BTW, it's implied that the two of them are a couple, so there are a few sweet and subtle Yuri moments.
