An insider revealed, "Krystal will be appearing on tvN's 'Sensible Prison Life'. To be honest, the drama revolves around men and there aren't many female characters, so it's hard to say she is a leading character. She is just the female character with the most screen time."
PD Shin Won Ho is the man behind the 'Reply' series. This will be his new project out of the 'Reply' series and will air in the fall.
