Ami seems to already be hanging out with Maya:
So, they are probably fine. Maya only really gives a shit about Ami and Sensei, so this was inevitable.
Noriko is supposedly Ami's "sister" along with Niki:
And has apparently always planned to live happily ever after with Ami and Sensei:
So, I can definitely see this relationship growing. Especially with Niki being important to Ami, and all 3 being important to Sensei.
Futaba doesn't really seem in the mood for friends lately. Even a little annoyed by Rin it seems. Albeit, she's cozying up to Otoha now which is... strange.
A little out of left field, but Nodoka and Otoha might be getting closer to Ami soon. Not only are they into incest, depravity, and Sensei, they also know about her mother, and Nodoka, in particular, is interested in Ami:
They also both have some relation to Niki. Sensei even seems to struggle between choosing Niki and Nodoka:
So, this is sure to cause some drama. Who knows, Nodoka might even be trying to be Ami's "sister" soon as well. She already calls Sensei "papa".
Otoha also seems interested in Maya, Niki, and Sensei, and has some connection to Sekai. It seems like she'll probably get involved with Ami at some point.
Overall: I doubt the "burned bridges" will be that big of the deal. Most of these girls just want Sensei's dick and don't really see Ami as much more than a way to get it, which isn't exactly new to her:
Ami's relationship with Uta might be a little different now due to the whole breaking into her house, trying to kidnap Sensei, and having her wizard pic on Sensei's phone stuff, though.
Ami will also probably be wary of Chika, in particular, since she sees her as possibly the most obsessed:
Still, they will both probably play nice because it's beneficial.
In the end, it'll really just depend on if Sensei will honor his word and prioritize Ami now:
Otherwise things will probably just repeat themselves, and none of what's happened will matter much.
