RiO and 52Hz are not only teammates on stage but also a real-life couple, bringing surprisingly cute and "fateful" moments in the show.
According to the team dividing results, 52Hz was chosen as the guest of the Phuc Du team, while RiO was also in the same team.

In particular, in the "Dating up Fate" game, the rules require members to quickly group together so that the total number on each person's shirt is equal to the number given by the MC.
In one situation, RiO chose to pair up with buitruonglinh, leaving 52Hz unused in the middle of the stage. Another time, when 52Hz was paired with Khoi Vu (with a total of 7 points), RiO suddenly appeared wearing the number 4 shirt, causing a situation where the "third party" was crying and laughing. In the end, 52Hz still chose to return to her husband RiO, abandoning KhoiVu. This image of the "love triangle" was quickly shared on social media with a series of funny comments.

Episode 7 will air on November 1st, which will be the first performance stage of Phuc Du team, where the couple 52Hz and RiO officially appeared together in a music performance that promised many emotions.
