After School's Lizzy appeared as a guest on the recent episode of SBS' "Strong Heart", where she charmed the set with her Pusan dialect and�bubbly nature. Lizzy also expressed her thanks toward Yoo Jae Suk, which�provoked Kang Ho Dong. Lizzy had written an intriguing message, 'Teacher Yoo Jae Suk, thank you', onto her bulletin board. She went on to share her story:

"I recently appeared on KBS' "Happy Together", and MC Yoo Jae Suk aided me a lot. He told me to relax and just be myself, and many people started to show interest in me after the show. I often think that the show saved me. The number of members in the fancafe rose as well. Thank you, teacher Yoo Jae Suk."

"When I was an elementary schooler, Kang Ho Dong came to a supermarket event in Pusan as the host. The reason why I call him 'ahjusshi' is because I feel as if we are friends. If the nickname offended you, I apologize."
