The blue and yellow teams were given the mission to race against the clock to become the last remaining 'heir' of the 'RM Group'. The still cuts show sparks possibly flying for the 'Monday Couple' again and Kim Woo Bin and Choi Jin Hyuk showing a little bromance to combine their strength to pull the plunger off of the wall. It's said despite their best efforts, the two's seemingly clueless nature at times had Lee Kwang Soo remarking that the two could even take the place of the 'easy brothers'.

Park Shin Hye will also give girl groups a run for their money by showing off her surprising dance skills during the cast's invasion on the 'Cultwo Show'. 

As mentioned previously, Song Ji Hyo, HaHa, Kim Jong Kook, Lee Kwang Soo, and Ji Suk Jin are on the yellow team, while Gary, Kim Woo Bin, Yoo Jae Suk, Park Shin Hye, and Choi Jin Hyuk are on the blue team.

It all begins on the 6th at 6:10 PM KST, so make sure you catch the trio of 'Heirs' try their hand at variety!
