These three episodes, along with episode 13, are probably my favorite in the series. They show where the author’s strengths are, imo. She’s excellent at writing people and their interactions with others.
I recently binged all of the volumes available in English (1-9) and bought the available Japanese manga (1-15) and character guide to try and help support the series in my own minuscule way. I really love it so much and wish it would get a second season one day when the manga has progressed a bit more, but it doesn’t look likely. One can live in hope, though.
