Anyone Has at Least One F in Their Heart, Right? Oh, Not a Grade—It's fromis_9;; 🙄💯 | The Silence of Idol | fromis_9 'Supersonic'

Fromis_9 must practice the choreography for “Supersonic”. Whenever the instructor enters the room, they must quickly hide. If a member gets caught, he receives a “punishment”. If the members manage to dance all the way to the end, the group passes the challenge and gets to take a nap. Otherwise, the entire group receives a collective punishment.
