Rose? Nishino bought Takeuchi's lies about Rose so he thinks she's a bitch.
That leaves Rose to approach through third parties. For example when Nishino asked her to introduce her to a girl that girl didn exist, it was a fake made so Nishino could send Rose his photos.
Now Shimizu lied Rose about Nishino going to the party. Why? Because Shimizu wants to be with the popular group of the class, so if she gets Rose shell curry their favour, also she wants Takeuchi to bang her that much she will risk herself to accomplish that goal.
TLDR she's horny and will think with her vajajay.
