Ohhh you right, nice observation
Well, they would have been invited if they weren't a "victim" too. That person had to suffer working all day during holidays despite being the more qualified for the scholar ship than idiot 2, who was the 2nd to die in the last murder series, btw. The sis who came along that person when uke skipped classes and went mia also wasn't invited cause same reason, tho the other was a but closer to uke (like more 1 on 1 talk about favorism, or revealing their parents shitty situation and if uke has something he wants to talk about they are open for it)
Btw, I believe that person is a girl, may not be easy to regcognize but it was implicity said, like when they were talking 1 on 1 and uke's dumb classmates saw it and were all about how girls ame boys can't just be friends
Yeah I read a little more and saw that part about her being a girl (just before he burned the asshats)
I was wondering why the one friend was saved and not invited to the party. If you read chapter 19 he was the only person who actually respected their wishes of not entering the study. And he's the only one who was not trying to stick up for the other idiots. He was the only one being respectful and doing exactly what the main characters wanted.
