Translator-san, please, no need to apologize. Take as long as you need, I'm just thankful this is getting translated. (and I'd just like to remind people an official translation will be available starting in 2021 btw, so buy it if you can)
Kind of a sad/reflective chapter, but I loved the very deep conversation with the friend outta nowhere during lunch lol.
As for the new character, honestly, these two need a bit of a push to move forward and it's difficult for a sister (even one as great as Subaru) to do that, so I'm excited for the possibility of greater relationship progress. I want these two to get together asap, so we can enjoy them as a couple for a while before the manga ends.
