During the event, Lee Kwang Soo introduced himself, saying, "I am Lee Kwang Soo, playing the role of Jo Suk who is an aspiring cartoonist." He also commented, "I really like webtoons so I felt more pressure. I talked to the director a lot before filming, and I received a lot of help while shooting." 

He continued, "The director said before filming that there would be a nude scene, so I was preparing myself...I thought, obviously, it's going to be shirtless scene, but it was a pantsless scene. So I guess you could call it a preparation. I prepared my body." 

'Heart of Sound' will air on November 7 through Naver TV Cast.
