Rainbow's Jisook shed some emotional tears talking about her mother who passed away last year.

On the February 21st episode of SBS 'Strong Heart', Jisook began tearing when she saw Kim Boosun display her love for daughter Lee Miso who guest-featured on the program with her.

"My mom passed away last summer," Jisook remarked. "She was battling cancer, but at the time she told me she was only being admitted into the hospital because she had a bad case of the flu."

"She didn't tell me the truth because she thought she would become a burden to me and affect my work," she continued. Jisook thought the sky was caving in when she heard the news when it was too late.

"One day after a broadcast, I got a call saying that she was unconscious," she said. "It was like something out of a TV drama. It was the first time I had seen her in a while, and she was so thin."

"I kept telling my unconscious mother how much I loved her... but she didn't make it," she managed to say, as the tears began to flow. "My mom loved me so much. She's the reason I grew up to be so bright and optimistic."

Also on the episode were Yoon Jong Shin, Seo Jihae, Kim Boosun, Shin Daeun, Kim Joohee, Kim Kyung Min, Girl's Day Minah, A-Pink's Bomi, Dal Shabet's Subin, and more.
