So Kim Soo Hyun will be getting two new actress costars he’s never worked with before in his next drama Knock Off. Earlier it was announced that Kim Si Eun would be the female lead and now Jo Boa joins as the second female lead. Kim Si Eun is an up-and-comer with solid rising cred while Jo Boa has been female lead in multiple dramas already to mixed results. If this is the confirmed main cast I’ll keep my mind open that it will deliver the viewership ratings and interests that any Kim Soo Hyun drama is sure to generate.
