He commented, "I saw the video, and I laughed all day because it was so funny. I didn't think my voice and Tae Jin Ah sunbaenim's voice would be similar." Tae Jin Ah was also shown the video, and he said, "It's very addicting, and I like it. This is a song Rain released after being discharged from the army, and it's daebak. I sing the song when I go to karaoke, so it's that good."

Both artists expressed their desire to do a collaboration stage, and even though Rain has a lot of overseas schedules, this stage may be one worth seeing!
