10th episode of "Youth with You" starts with a dramatic phrase narrated by youth producers representative Kun: "Today nearly half of our trainees are leaving us."

Then it switches to a few scenes in which we can see trainees crying and encouraging those who ranked higher than them. Intro ends with words:

"Those who leave are learning to say goodbye, and those who stay are saying goodbye."

Then Kun takes the microphone and says: "From now on, all of the votes you won earlier have been reset. It means you can't just rely on what you won earlier and stop improving yourself."

Later we learn that the next elimination round, the group battle will "cut" another 24 trainees.
