"South Korean Foreigner" had Girls' Generation's Hyoyeon and Sunny and Lovelyz's Mijoo and Kei as guests.

On the September 16 episode of the quiz show, Kei and Mijoo stated that the Girl Generation are their role models. For Kei, since Girls' Generation is the longest-running girl group, she did not have any idols when she was young.

Kei wants to shine in the industry for a long time just as how the Girls' Generation did. They are her role models, and when it comes to skills, they are also a legend in every way.

Moreover, the show asked for the Girls' Generation's side to advise Lovelyz. Sunny stated that they should be careful about people. They have to be cautious about men too. Meet them in secret.

Sunny added that she would tell more details to them in the waiting room. At the same time, Hyoyeon commented that their health is the most important thing.

As Lovelyz asks for more advice, Hyoyeon recommended that they talk if there is a problem. Kei answered that the Lovelyz is the type of group that talks about things right away if someone from their group is upset about something.

During the show, Sunny also shared some Girls' Generation's rule. The rules include their "five-minute talk," where they talk for about five minutes at the end of the day. They also promised that if they are separately promoting like they are doing now, the group should again meet at least once a year.

The MC asked which member they think would be marrying the first, Hyoyeon answered that she believes that it is her. When she was asked about her dream in the past, she replied that it was a good wife and mother.

Hyoyeon thinks that Sunny will get married second because she has been taking care of her plants lately, so she wondered if she is getting ready for marriage.
