On November 28 episode of KBS' music show 'You Hee-yeol's Sketchbook', GUMMY made a guest appearance.

GUMMY said, "I still can't believe that I've become a mother. It's so hard to believe."
She continued, "Even when I see my daughter in front of me, I'm like, 'Did I really give birth to her?' Every day feels like a miracle."
She laughingly went on, "Although I don't feel too ready to sing again, I thought I should warm myself up with this show."

She said with a smile, "I used to sing a medley of popular children's songs to her, and I still do."

After being together for about two years, they made their relationship public in 2015.
Then in October 2018, GUMMY and Cho Jung Seok married each other and their first child was born this August.
