Super Junior's Kim Heechul talked about his cameo appearance in SBS drama "The Heirs."

The October 24th episode of JTBC's "Ssulzun" featured guests such as Kim Soo Hyun, Moon Young Nam, Lim Sung Han, and Kim Eun Sook.

In this broadcast, Kim Heechul said, "(I asked writer Kim Eun Sook) about romantic comedy replication."

He said, "Kim Eun Sook responded with, 'It is true that is a romantic comedy clone. However, it's not just something anyone can do. Only I can write things such as the foam kiss, and lines such as 'Let's go, baby' ."

He continued, "She also said, 'I started with replicating and developed it further. People who cannot develop cannot produce such works.'"

Kim Heechul also said, "After the first episode of 'The Heirs,' I received a phone call that said, 'Since we did an interview, you should make a cameo appearance in the show.' So I just returned from filming on the show, since I am the key to audience viewership."

Kim Eun Sook is currently writing for the romantic comedy "The Heirs."
