I wanna see a story where the girl bully is SUPER tsundere and gay for the cute innocent girl she's bullying (partially because she hates seeing boys hitting on her)... And then, when she's in the process of bullying her, she finally looses it and flat out says "why won't you f*cking look at ME?"
Your dream got fulfilled pretty much. Read "Bully and Bullied"!
I also love this trope. "Bully and Bullied" is awesome, I love it. But, I'm greedy, and I want more
Graphite by Takemiya Jin is pretty short but it's also about a tsundere bully, with a little bit of a twist. I really like the way it portrays sensuality in BDSM as well, quite beautiful.
