We see the preparation of the teams to carry out their first mission, called the "Connect Mission". Each team chooses a leader and she distributes the different parts of the songs, the most important and desired positions being the main vocalist and who will have the "killing part". Then they are evaluated a first time by the judges in their practice rooms and we see the changes they make after receiving this feedback, in addition to this generating a first ranking between all cells. In this episode we will see 4 stages, those of the songs "Yes or Yes" and "How Yo Like That". (Source:Malu at MyDramaList)
