My Little Ones (Please), It's Time to Go to Sleep 😇 Even the Instructor Becomes a Kindergarten Principal in Front of TREASURE! | The Silence of Idol | TREASURE (트레저) 'HELLO'

Traesure must practice the choreography for “Hello” while trying to avoid being caught by their instructor. Whenever the instructor arrives, they must quickly return to their beds and pretend to be asleep. If a member is caught, she receives a “punishment.” If at least one member manages to complete the choreography from beginning to end, even alone, the group passes the challenge and earns a nap. Otherwise, the entire group receives a collective punishment.
