MBLAQ's LeeJoon had started off with the variety world with the coldhearted hidden camera.
On the episode of KBS 2TV's 'Invincible Youth' broadcasted on the 7th, LeeJoon had fallen for hidden camera planned out by Kim TaeWoon and G7 (Yuri, Sunny, Narsha, Han SunHwa, Goo HaRa, HyunAh, HyoMin) when he came out as a guest on the show.
On this episode, the G7 members and the guests Jung JunHwa and LeeJoon had left for the different mountains and the rivers in the process of going to investigate the village. However there had been a happening where LeeJoon, HyoMin, and SunHwa who spill the maple syrup they had collected accidently.
When this happened, Kim TaeWoo, Narsha, and Sunny thought about doing a hidden camera while they were planning. On this episode, because LeeJoon fell for the acting by Narsha and Kim TaeWoo, he ended up singing, dancing, and even making fun of himself in order to lift up the tense mood between them. And watching this happen, the filming set had burst into laughter.
Also on this day, thanks to Sunny who had made the mood between Kim TaeWoo and Narsha more serious, HyoMin and SunHwa had also fallen for the hidden camera leading to laughter in the end.
When LeeJoon found out that this had all been a hidden camera, his legs unbuckled and he fell to the ground saying, "Do I have to tell this to JiHoon hyung (Rain)?" causing laughter once again.
