Jihyo said, "I heard that while I'm sleeping, I've talked on the phone and even sung.  Sana is in my room, too, and Sana suddenly got up and shouted our group's slogan.  It was really scary.  Tzuyu normally sleeps in a proper position, but one day, she said 'kiss' while sleep talking.  I don't know who appeared in her dream."

Taken aback, Tzuyu said, "I don't know.  I don't remember."
