I thought this was a message from the mangaka to the audience that there’ll be no confessions as it’s going to be an adult implied relationship but then he flips it.
Not gonna lie thought we were going meta there lol
@gabrielaguilar519 That's actually the exact hoodie that he's wearing at the start of chapter 42 when he's reading Yamada's favorite manga and realizing that the love interest is basically a taller more confident version of him and then gets to the scene where that character calls out that the protag likes him based on her fluttering around him all the time only to flash back to several instances of Yamada fluttering around him all the time. Norio drew it as an advertisement since they're making that hoodie real and selling it.
"Are we just going to go out like this without a confession, like adults?"
"No."
"Okay, I'll wait for you then."
I think the meaning of the conversation on page 3 goes something like this
