Alright, I wrote a comment on this chapter 3 years ago and it was really dumb.
On reread, I still find this development quite annoying, but more so just because it is overly angsty, but that is not limited to just this development, as The manga as a whole is just very angsty.
Though I do find it confusing, as if they met in high school, that means the whole drinking party was when they were middle schoolers?
