In the sbs entertainment program All The Butlers' broadcasted on the 18th, 33 years old MC Lee Geum Hee appeared as a Master.
Lee Geum-hee began to teach the members to pronounce the Master of "How to speak well." Lee Geum-hee's attention was the accuracy of vowel pronunciation. Lee said, "When pronouncing vowels, it is roughly spilled to pronounce economically. In fact, '' is a pronunciation when putting a large lettuce in your mouth. "
Yang Se-hyeong emphasized the vowel, saying, "Is not this the way it is? Yes?" But he laughed at the scene with a somewhat malicious tone. Yang Se-hee later praised Lee's pronunciation of Yoo Soo-bin, not himself, and added, "I do not think I'm doing it because I am sick."
