Jimmy Yoo's (Yoo Jae Suk) project to launch a girl group on MBC's "How Do You Play?" continues with the proposed group Refund Expedition composed of members Lee Hyori, Jessi, Uhm Jung Hwa, and MAMAMOO's Hwasa.

During an episode, producer and entertainer Lee Sang Min met with Yoo Jae Suk and advised him on SSAK3 earlier this summer. He shared that the producer should take care of the relationship between the four members. The four of them in the group are enough, but he has to make sure that a fight will not break out between the four group members.

Uhm Jung Hwa and Lee Sang Min worked together when she went through at least two boyfriends. Meanwhile, Jessi is said to be the most difficult one. On the other hand, Lee Sang Min knew her before she debuted, saying that her voice is fantastic, but her personality stayed the same.

Moreover, Lee Sang Min talked about Lee Hyori's husband, Lee Sang Soon, and discussed how being caught dating in public is a violation of an artist's contract. The two talked about how there is an article stating that there would be no violations if the one your partner is more famous than you, adding that artists were told never to go on dates near the Han River in Jamwon because most reporters will always be there.

Lastly, Yoo Jae Suk gave the members their official stage names. Lee Hyori is "Chun Ok," Uhm Jung Hwa is "Man Ok," Jessi is "Eun Bi," and Hwasa will be "Sil Bi."

Afterward, Lee Hyori sang Uhm Jung Hwa's "Invitation" with Lee Sang Soon. She then continued asking Yoo Jae Suk why he did not interview So Ji Sub for the position as a manager she had requested.

Meanwhile, Hwasa made everyone hysterical by continuing to eat despite the argument about the manager position. When Jessi answered that she did not understand even one of the contract because it was written in Korean, Yoo Jae Suk gave Jessi a surprise Korean Test.
