Afra Saraçoğlu portrays Çağla Öncü in A.B.İ., a determined lawyer whose belief in justice gives the early story a strong moral centre. Çağla is connected to a painful family history, but she refuses to let that past control her choices. Her intelligence and sense of responsibility bring her into the Hancıoğlu family’s complicated world, where legal truth and personal loyalty often collide. Saraçoğlu presents Çağla as thoughtful, resilient and emotionally sincere. Her performance helps establish the series’ original conflict before the story expands into its later chapter of identity, revenge and new relationships.
