I know you weren’t talking about the main story. Hence why I said “extra chapter” and not just chapter. That extra chapter was never a glimpse of their future lol. It also never said anything about it being the future, you can see in that chapter that they’re still living in the same place/room.
For some reason some people are confused thinking some extra chapters are a glimpse of their future when they’re not. It’s the author showing us scenes that happen NOW, just didn’t put it into the main story since it wasn’t important for the plot. The chapter you were specifically talking about isn’t a glimpse into the future

Also to confirm: the chapter you talked about is chapter 25.3 labeled as an extra. The very first page (not the scan credit page), says, “This month we bring an extra chapter! This is what Yoshino and Kirishima’s everyday life is like.” In a text right next to where there’s a panel of her feet (the same scene kirishima saw and got scared).
i am praying for the creator/artist that they will always be healthy, happy, and eating and sleeping well. y’all don’t understand when that chapter showed what their marriage would look like in the future (the one where yoshino fell asleep by the entrace door and kirishima literally dropping the cake just to check if yoshino’s heart is still breathing) I AM OBSESSED!!! i’ve been patiently waiting for new updates for years now but it is worth it (▰˘◡˘▰)
