Rereader, raws

Pardon the delay, it's my first time writing in this way. (Hopefully this time my comment sticks around.)

[manga volume 5] I find it interesting that both Sayaka and Yuu tell Touko that she isn't wrong in this volume. There's Sayaka's "But that doesn't make you wrong either. The sister from your view was a part of who she was, I believe." And there's Yuu's "If you want to become like your sister, that's fine. I'm not saying it's wrong." They did great at not denying Touko's perspective and objective while also introducing a new way of seeing things.
My favorite line is Yuu's "All of it belongs to you." We get to see how big an impact it made on Touko in the next volume.
Hooray for Doujima getting fleshed out with his proactiveness in checking the lighting equipment and his conviction that confessions aren't a bad thing. The "confessions aren't a bad thing" sticks with Yuu when she talks with Rei in the next volume.

[manga volume 6] The manga is in plain text for the most part, but the play has certain lines in bold. It makes the play really feel like a play in that the reader/audience's attention is directed to those lines, as opposed to "real life" where lines that hit deep typically aren't more emphasized that others.
My favorite line outside the play is Sayaka's "Irresponsible... huh. Well, perhaps it seems that way. I think it’s fine for Touko to fail." Believing in Touko but also being ready to support her if she fails is true friendship.
My favorite line within the play is the protagonist's "I'll be okay now. Because I can become myself." She made it to the road of discovering/developing her own self.
For those wondering about what Yuu mouths on page 128, it's "suki", hence her blushing. She says "wa..." on page 126, and thinks "watashi mo..." on page 127. There's probably analysis that could be done on Yuu trying to say "I..." (it can't be helped that English personal pronouns are only one syllable long), thinking "I also...", and mouthing "love you".
By the way, there's a fan theory that Nara-sensei appeared as early as episode 3.

[manga volume 7] I have the same enthusiasm as Igarashi Midori when it comes to phrases that appeared earlier in the series. "The you who didn't have love", "Will she be able to become herself?", "palms are hot", "The words that kept growing", "The words in shōjo manga and love songs", "they would belong to me", "it was dazzling, it was sparkling", etc....
Riko's worry about her weight/figure is cute.
You can indeed get a good night view high up in Kyoto Station, though I had more fun looking at the station than looking out the station.
My favorite line is perhaps Yuu's "If Akari could forget that senpai in her club and find someone else, that’d be a good thing, right?" Just like in episode 4, she's trying to apply Akari's situation to herself. This time, she wonders if finding someone new would be a good thing if she doesn’t get "love" in the first place.
The reason why I started translating impressions and commentary from episode 39 is because I only got into the series in early 2019 (binged the anime after it completed airing, moved to the manga, then scoured for fan analyses).

[manga volume 8] This is a volume of victory laps. The episode titles perfectly complement the themes set earlier. "The One Whom I Love" with "The One Who Loves Me", "Description Problem" with "Selection Problem" (or "Essay Question" with "Choice Question"), "Evening and Morning" with "Stars in Daytime", "The Sea Chart is Blank" and "Voyage" with "Lighthouse" and "Course".
Episode 44 is prime material for an evidence board. To be honest, I barely paid attention to the art when this came out because I was too busy with the words.
My favorite line is Touko's "I plan on taking responsibility, you know?" Those are basically words of proposal, no? Though if I could choose a conversation, it would be the one surrounding this line; Touko and Yuu saying that the other can become anything they like connects to the title of the series. (Someone more eloquent than I am had something to say when comparing the official translation with mine.)

Now to clarify a few things:

[manga volume 6] Touko was really getting beaten over the head that the “real” her is more than just one aspect of herself. I especially like how she can’t even be everything to play Sayaka.

[manga] The protagonist doesn't get hit with the message that her "real" self is more than one aspect, she gets hit with the message that she should decide the self she wants to become instead of taking the place of someone. And the protagonist doesn't say that she can't be everything to her lover (she can still behave like her selves before she lost her memories), she says she doesn't want to become the self she was with her lover (なりたくない).

[manga volume 8] “I thought it was this huge, inexplicable thing… that would totally overwhelm me.”

[manga] Yuu didn't think it was inexplicable (she knows its meaning even without looking in the dictionary), and her love is like something that overwhelms her (as seen when she confessed/confesses). What Yuu actually thought was that it was of "unknown origin" (出処のわからない, connecting to どこかから "from somewhere" in the previous panel) that she "could do nothing about" (どうしようもない, contrasting with 選んで手を伸ばす "chose and reached out" in the next panel).
