As for Shin Bora, she gave a lot of specific advice, making everybody laugh. She said, "The gist of Kim Gu Ra's words are that he wants to take a break... Honey Lee gives a lot of love, and I'm used to it. It can feel a bit burdensome when she suddenly touches you, but she doesn't force it...�Min Jong oppa is bad at everything."
