On February 28, she left a message through her managing agency, Signal Entertainment Group, saying, “I would like to send my most sincere gratitude to all of those who have loved and cheered on ‘I Have a Lover.’ I especially adored this drama because I had to act two parts, and I can’t believe it’s already over. I hope many people felt happiness while watching ‘I Have a Lover.’ Thank you for loving Dok Go Yong Ki and Do Hae Kang.”
In the drama, Kim Hyun Joo took on the role of the two completely different twin sisters, Dok Go Yong Ki and Do Hae Kang. She was praised for her exceptional acting, having made it difficult to believe that the same actress was playing both characters. Fans also loved how she skillfully expressed the internal conflicts and concerns that went through Do Hae Kang’s mind regarding her relationship with Choi Jin Eon (Ji Jin Hee).
