I have two children. Six months ago

I have two children. Six months ago, they both lived in Jeju,
but they just moved up to Seoul together. My daughter is the
oldest. She is 22 years of age [and] studying design in Seoul.
My son is 16. After finishing high school he moved [there] to
study singing and dancing. He really wants to be a famous
singer. Right now, he has made it past the first two of three
auditions for a singer training school in Seoul.
