I made a small but crucial omission in the translation on page 21. I didn't realize it until I read the comments here and on r/manga about how Amano shut down Sachiko and her friend. Under the text bubble that says "Ah", the raw had "tsuiguchini" or "I said it unconsciously." So it wasn't intentional. Amano wasn't slamming on Sachiko. It was just Amano being the same sad sack Amano saying the wrong thing at the wrong time... Sorry for the confusion.
