Satoru sits, paying attention and trying to not think about the music and the technical details. Having just Suguru's side of it does help, especially because it's discordant without the harmonies of Satoru's part laid through it. It forces her to just focus on Suguru and what she's bringing to the song.

By the end of it, Satoru has made some sense of the emotional beats, though the conclusion she's come to is probably not the one Suguru was hoping for.

"Okay. Yeah. I think I see the problem." Satoru gives her a bit of a reprimanding glower. “I think the problem is that this song means something to you, so you’re putting actual emotions into it, because you know what it’s about and it’s significant. But I’m not matching you, and you want me to just make some up?” Satoru rolls her eyes. “You’re such a moron. Okay. You wanna tell me the story behind the song now, so I can find something appropriate or, I guess, fake it better?”
