Looking for manhwa

I remember seeing the promo(?) of this story floating around somewhere but it goes a little like a typical villainess story where she wants to steal the ml. The plot twist in the story is that they're stuck in some sort of "show" format where the villainess doesn't really like the ml and has to act like she does because the plot is forcing her if that makes sense. In this plot the "show" that they are stuck in the ml wants nothing to do with her but in reality he really likes her and she hates him. I believe the villainess has purple/black and the ml had brown or black hair. It might be a school setting and is possible a promo. The vibes are inso's law but the mc is thr "villain" pls help </3
