Sandeul bursts into tears on ‘Strong Heart’ thinking about his grandfather

B1A4‘s Sandeul burst into tears on the January 15th installment of ‘Strong Heart‘.

On the show, Kim Jung Hwa talked about her mother who passed away due to cancer. While listening to her story, Sandeul had shed tears, and the MCs asked what was wrong. Sandeul had to take a moment to compose himself, and he had a hard… time confessing, “My maternal grandfather has cancer, but he can’t even get surgery“, revealing that the cancer was untreatable.

He continued, “But my grandfather doesn’t even know he has cancer. He can’t get surgery, and he’s such a cheery person that we thought it was best not to tell him, so we haven’t. Everyone in our family pretends they don’t know anything.”

Even after he was done, he couldn’t stop crying. MC Shin Dong Yup tried to make him feel better by joking about their upcoming topic, but in the end he couldn’t stop crying and actor Park Shin Yang suggested they take a break from filming before they continue.
