On the third day of the Ramyeon of Life Restaurant, Lee Hyo Lee and Lee Sang Soon from Jeju Island visit the place to taste his unique yusanseul ramyeon. Hyo Lee and Jae Seok show off their good chemistry to draw attention. After that, he is invited to a cooking show as a chef and reveals the recipe of yusanseul ramyeon. His poor cooking skills make the staff feel embarrassed. He also meets Pengsoo to visit his new house built inside the EBS broadcast station. Stay tuned!

This time, Jae Seok and his crew decide to look for a new alter ego for Jae Seok to entertain viewers who are exhausted from the COVID-19 crisis. After discussing with Sang Min, Ji Hye, Sung Su, and Il Sang, Jae Seok heads to Jeju Island to talk Hyo Lee and Sang Soon into joining his mixed gender dance group for the upcoming summer season.

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 Superstar Stylist, Han Hye Yeon, visits the show to give SSAK3 the ‘90s look. The members feel shy when they first see the fancy outfits. However, they soon become one with the outfits and start to fight over the center stage. As expected, Linda G takes the center while the other two members reluctantly try their best to assist her.

After thorough preparation, SSAK3 heads off to shoot a music video for their cover song, “In Summer” by Deux. As expected, Caregiver Hwang also joins other members to complete the bundle. Although B-Dragon gets constantly bullied by other members, he is willing to take the humiliation in order remain center stage.

This time around, Sang Soon visits the show as the songwriter to complete the recording of Summer Ocean Again. While doing so, B-Dragon does everything he can to attract all attention to himself. In the end, Linda G and U-Doragon lose their temper and complain about his self-centeredness. Nevertheless, B-Dragon is determined to stay in the spotlight.

Although U-Doragon wants to minimize the budget for SSAK3’s music video, the two other members want it to be as fancy as possible. Moreover, U-Doragon might not be as experienced in shooting music videos as Linda and B-Dragon, but he still shows off his unique skills. Meanwhile, they make a pledge to do an unprecedented challenge if they win first place in a music program.

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.”

The squabbling among the three members of SSAK3 doesn’t seem to stop even at the last practice before the debut. With Upset Rain on the verge of bursting into tears due to continuous bullying, they officially debut on Show! Music Core. When all fellow singers gather on the stage for the final score, the members of SSAK3 realize that they are on the list of first place candidates.

After weeks of hating and nagging, B-Dragon and other members of SSAK3 gather for their final performance together on a music show. While other idol groups are surprised at their unprecedented, fancy meals as well as U-Doragon’s surpassing live performance, SSAK3 waits for the final score as one of the first place candidates.

After a short but exciting roller coaster ride as SSAK3, the members meet for the last time before their disbandment. As a special treat, B-Dragon prepares a feast of abalones, wishing the older members a brighter future. While Linda and U-Doragon respond to him with gratitude, a surprise, tear-inducing gift from the fans awaits them.

The members of Refund Sisters gather to shoot the music video. Man Ok’s enormous outfit brings back good old memories, while other members show off their unique charms as well. When the girls are busy doing their best, the director asks Jimi Yu to quickly film a short scene without the members’ knowing.

Due to the severity of the global crisis, the members of Refund Sisters never thought they could perform in front of an audience.

At the end, when the members watch KAFNA’s cheer squad perform, their eyes brim with tears.
