On August 9, Yulhee went live on Instagram for a Q&A session.
During the Q&A session, she was asked many questions about her newly-born twin girls.
One of the questions was, "How much did the girls weigh when they were born? My daughter was born underweight, and that really worries me..."
She continued, "Actually, Ah-yoon's was not born healthy. There is a little issue with her body, and we're keeping a close eye on it. But she's fighting it very well."
She added, "Don't worry too much. Babies are stronger than you think. Just give her as much love as you can."
Then back on February 11, the couple welcomed Ah-rin and Ah-yoon into the world.
