Hasn't that already kind of been happening to her for the past... i don't even know how many chapters every time she ineracts with Shizuki?
It's kind of interesting to see where her story would go cus it's mostly been her trying to apply her world view on the three others but them basically being immovable and ending up rubbing off on her instead.
Tries to meddle with MC - gets shot down or seen through every time, and instead ends up getting genuinely touched by some of MC's actions
Tries to meddle with the two girls - they "include" her instead by indirectly forcing her to be part of the volleyball team effort, and, in stark contrast to her current or past friends, aren't afraid to call her out directly instead of behind her back, and for a good intention instead of to hurt her (even with Kusunoki indirectly throwing shade). Romantically, she thought she could provoke them but Otobe ends up sacrificing herself for the greater good.
Now, with Otobe and Keisuke basically being unswayable, It seems the only person left she might be able to provoke is Kusunoki. Is she gonna succeed at making her jealous, or is she gonna hit a brick wall like she did with the other two, and end up becoming the one who gets changed herself? Or is it gonna be a bit of both? It would be interesting if the climax becomes one between Snek with a bit of kindness vs Kusu with a bit of jealousy, with the two of them both having rubbed off on each other and changed by the people around them.
