>Because she's only "in love" with Sakurako's superficial looks and pretend assertiveness.
There's nothing wrong with this. Good looks show she cares about her appearance and confidence shows she believes in herself.
In a slut-taming story, the slut being shameless is actually a good thing since it makes the conquest more satisfying. It's not like Sakurako is a particularly good person either. She tried to seduce her old crush solely to get revenge and is faltering because of how hot she is. They honestly seem perfect for each other. Besides, Sakurako moving on to someone better would just make for a less interesting wish fulfillment story.
