Newer Mitsuru and Aigis friendship ranks.

I don't know if someone else has discovered this, but in Rank 8 of Mitsuru's social link before confronting her fiance there is an option that says "never meant to be" or something like that and this option changes the dialogue when you confront her fiance and also leads to a newer rank 9 that locks you out of the romance. The same happen in Aigis route in rank 8 if you choose "friends" after she explains to you her feelings.

Until now I haven't found a newer rank for Chihiro and Yukari, but Yuko, Yamagishi, Mitsuru and Aigis have an alternate route that locks you out of the romance option.

Yamagishi rank 7 romance flag: " is that the only reason?
alternate route: " that's probably it"

Yuko rank 7 romance flag: "wanna make that true?"
alternate route: "They are just joking"

Mitsuru rank 8 romance flag: "that's up to you"
alternate route: "it's not meant to be"

Aigis rank 8 romance flag: "it's love"
alternate route: "because we're friends"

I haven't found in Chihiro and Yukari their platonic routes, but maybe they are between rank 5 to 8
