I do only remember that the Heroine cut off the Black Haired Male Lead upon their first meeting after he somehow got mad at her or somebody. It’s kinda a Love Triangle wehre’s a Schools like “White Prince” wich the Heroine likes and the Black “Prince/Monster” wich is the Male Lead (Those two are best Friends and the ML is like the idol of the White Prince). Somewhat the Heroine and the ML end in the same dorm and they have kinda an (unhealthy?) relationship wehre the ML like kind of Bullies her.
