Curate, connect, and discover
I’d consider sitting at 5, 8, and 12; they're all pretty chill, and I like pretty much all of them. A much as I love Kokichi, and Byakuya; Fuyuhiko and Kokichi would no DOUBT fight like children and Byakuya would probably just sit there and give them dirty looks.
and 7 would just be a disaster. Nagito’s love/hate for Junko would probably lead to them physically fighting while Miu laughs at them and makes dirty jokes.
I would probably sit at 2, 5 or 16
Stay away from 7
