On the September 10 installment, the three 'WGM' couples as well as one-day comedian couple Park Na Rae and Yang Sae Chan battled it out to see who was the best pair. They held a 'Show Me the Money' style rap competition, and Kim Jin Kyung especially surprised everyone with her diss skills.
She said confidently, "I'll ride this rhythm all the way through." Kim Jin Kyung did just that, defeating Eric Nam and Solar with her witty insults and even besting Park Na Rae and Yang Sae Chan.
The Jota-Kim Jin Kyung couple also beat the other couples in a 'Pokemon' game and let the others know they had the best chemistry.
