If the Villainess and Villain Met and Fell in Love, Vol. 4 (manga)

Yuri never mentioned having a younger brother, but a wandering Brigitte seems to have found him all the same. The boy certainly has Yuri's sharp tongue. And while his words cut deep, they offer Brigitte something she never thought possible-a way to speak with her contracted spirit. Brigitte wants nothing more than to finally communicate with hers, but the path there lies beyond the fire she's cowered from since that fateful day years ago. Does Brigitte have the strength to conquer her fear and walk through the flames to finally hear the voice of her very own spirit.
