Actress Kim Hye Soo of 'Signal' appeared on SBS powerFM's 'Cultwo Show' on June 22 and talked about the possibility of a second season!
She said, "The writer has to be really determined if she wants to do a second season of 'Signal.' The screenplay is no easy feat. Apart from that, I got the feeling the team was working really hard because they were all immersed in their [work] and in acting. That team all want to do [a second season]."
Hope to hear good news soon, then.
