(English) Born in Buyeo, Chungcheongnam-do and raised in Jamsil, Seoul. I went to Jamsil Elementary School when the Olympic Park was still a hillside village. I wish to be remembered as someone who tells fun stories with pictures. The picture books I wrote and illustrated include Singing Piggy, Rescue Mommy!, Stop the Fight!, Protect the Dream Factory!, A Strange Lost & Found Center, Dad's Strange Way Home, Mom's Strange Way to Work, Joyful Corner Store, Creepy Corner Store, Do You Think of Me at Work, Mom?, Do You Think of Me at Work, Dad?, Making Friends, What If I'm Wrong? Baseball Day, and Too Much to Worry.
