At long last, Bridgerton season four is finally upon us! The hotly anticipated fourth season sees fan favorite Benedict Bridgerton (Luke Thompson) get his love story with new character Sophie Baek (Yerin Ha). But will misunderstandings and meddling from other members of the ton ruin their chance at a happy ending?
