In this episode, Jae Seok and Ga In deliver their first duet at the Room Concert. Also joining the concert are Lee Seung Hwan, Sunwoo Jung A, Se So Neon, Simon Dominic, Code Kunst, Woo Won Jae, and Gray to cheer up those at home who are stressed and worried due to the recent COVID-19 issues.

After a breathtaking pansori performance by Lee Ja Ram, Jae Seok is introduced to another new alter ego. This time, Chicken Doctor Yu presents the viewers with the world of fried chicken. Expecting a flood of orders for his chicken, Park Myung Soo joins him to support him with his two years of experience in running a chicken chain.

While searching for the members for his mixed-gender group, Jae Seok successfully gets both Hyo Lee and Rain to join his team. However, he still needs a few younger members to complete the gang. With this being the case, ZICO, Kwang Hee, Code Kunst, and Simon Dominic visit the show to compete for the position by showing off their style of “Gang.”

Hyo Lee, Rain, and Jae Seok once again gather around to come up with their stage names and group name. From a list of intriguing suggestions, each picks the most appealing one. Meanwhile, Jae Seok is worried that Sang Soon might not like how Hyo Lee is quickly adapting to the flashy life in Seoul.

It turns out each member of SSAK3 has a completely different preference for a perfect summer song. Even the Myers-Briggs Type Indicator shows that Hyo Lee and Jae Seok should never work together as a group. However, what’s done is done. They have no choice but to come up with a song that can satisfy all three members of SSAK3.

Now that the members of SSAK3 have anonymously prepared the song of summer, it’s time for their songs to be tested among many other songs by trending composers. Meanwhile, the very last song on the table grabs Jae Seok’s attention. Although the composer still remains unknown, Jae Seok feels certain that this song will make a hit.

The members of SSAK3 are visited by Park Seul Gi as a reporter for the group’s much anticipated debut interview. The fierce competition for center stage doesn’t seem to stop until the release of the music video, “Summer Ocean Again.”

Although they are brothers, they are totally different from each other. Yaho prefers solely relying on the skills one has instead of one’s looks or popularity when it comes to picking his singers. Accordingly, Yaho decides to form a group of male vocalists. In doing so, he goes through a series of audition videos as he cherry-picks potential candidates.
