My Three Tyrant Brothers

The Ascania imperial family bears a curse that foretells their demise at the hands of a beloved soul. However, this spell is amendable only if a girl is born in the lineage. One day, a juvenile slave girl identified as Princess Chloe captivates attention due to her eyes that change color like an Ascania's. The family announces her as their little sister to break the curse. Overjoyed, Chloe looks forward to having siblings, but her brothers exhibit unusual behavior. For their safety, they have embraced a cold, emotionless attitude towards life. Will Chloe's advent stir emotions within them and inspire a positive transformation?
