After winning the 1st battle, (G)I-DLE was able to create the cue sheet for the second battle. (G)I-DLE's Shuhua chose MAMAMOO to perform first and AOA as the third performer. Jeon Soyeon decided to choose (G)I-DLE as the fifth performer. AOA's Seolhyun said that she was avoiding to perform second.

Oh My Girl was placed as the fourth performer and Lovelyz as the sixth. However, (G)I-DLE's Minnie created last-minute changes. She made AOA the second performer and Park Bom the third performer.

MAMAMOO listened to AOA's songs as preparation for their performance. They find the high notes amazing. All the members agreed to pick the song "Good Luck". Solar said that their songs were difficult to sing because they had many high notes. They picked "Good Luck" because they think it would suit them best and it is a nice song.

After listening to MAMAMOO's songs, AOA found themselves in deep thought. They considered MAMAMOO's songs to be very different from their own style. They chose to cover "Egotistic" because they fell in love while watching it.

Park Bom decided to cover (G)I-DLE's "Hann". She was hoping that it has hip hop vibes like 2NE1. She said she needs to get No. 1. She described that the supporter that she was planning to bring on stage was the best in competitions. She thinks that she will cry on stage.

Solar said something before going on stage. According to her, they practice and focused more because it wasn't their own song. Moonbyul said that all the groups' outfits are different. All of them will present a mini-concert.

As Moonbyul said, MAMAMOO members dominated the stage in their own way. Solar was startled by a sudden slip. The group's performance became successful in the end.

AOA had to face lots of challenges while rehearsing such as Chanmi's injury and Seolhyun's absence. They continued to work hard nonetheless. Seolhyun said before going on stage, "We'll show you a kind of performance that will make people say, 'AOA is doing this kind of performance?'"

AOA performed MAMAMOO's "Egotistic". They wore pantsuits that added to their powerful charms. They surprised their audience by adding a dance break. They earned a round of applause for their great effort.

Hwasa said that it was cool because they changed it into AOA's style. Moonbyul said the dancers were great. She said AOA's stage chemistry worked well together.

Park Bom was excited to unveil her cover of (G)I-DLE's "Hann". She managed to keep everything under wraps by doing closed rehearsals until the day of the performance. She said that she brought an expert in making an impact on the ranking. She said she was going to be No. 1.

Park Bom speared on stage wearing a powerful outfit and showed her rendition of "Hann." (G)I-DLE was very happy with her performance. They said that it fits her well. Park Bom's supporter is rapper Cheetah. She was amazed by Park Bom's rap and earned loud cheers from the other groups. Park Bom thanked Cheetah and said that she thinks she will go in the upper ranks.
