Hoseok arrives back in Songju which he left Songju a month before because his ankle was injured and he couldn’t work or dance. On that day, he had been waiting for the other boys to contact him. He realized that he always contacted them first, but did not want to this time. He remembers how he met Yoongi that night. On a whim, he packs a bag and decides to leave Songju for the first time in his life. But his mind was still there. He ends up in a larger city and gets a room at a guesthouse. He wanders around the first two days, and on the third day he ends up at a Citizen’s Hall’ where dancers are rehearsing. He watches a man dance and feels many emotions from his performance. A staff member asks him to leave because outsiders aren’t allowed in rehearsals, so he goes back to the guesthouse and thinks about the performance alot. He receives message from Jimin but he does not respond and neither do the other boys.
Hoseok watches the rehearsal the next day secretly, and then he comes back for the performance the next day. He notes that the man he saw at rehearsal didn’t perform. Later, Hoseok helps the staff to move stage equipment onto the train. The staff member recognizes him and sits next to him, revealing that the man Hoseok saw is their artistic director who used to be a dancer, but he was injured and couldn’t perform again. Hoseok ends up tagging along with the group and goes to three other cities with them. The director finds out Hoseok is also a dancer. Hoseok recounts how he got into dancing when he was twelve and his friends had dragged him up on stage. Hoseok thinks about how dancing makes him feel refreshing and rewarding because he could be happy and free. The director tells him that you have to go to your lowest low , escape it so that you can find your driving force, and hold on to it. Hoseok thinks a lot about those words. He also comes to know that the director is from Songju. Hoseok recalls the fireworks he saw from his orphanage and later from his apartment.
Hoseok turns down the offer to join the dancers on tour and decides to go back to Songju. He thinks that he might have not hit his own psychological low point yet, but maybe Yoongi had the day that Hoseok abandoned him when he was in despair. He messages Yoongi to ask if he’s okay. Yoongi responds with a music file the next dawn. Hoseok listens to it and thinks it's the most beautiful song Yoongi has ever made and resembles Yoongi. Yoongi asks Hoseok when he’s coming back. Hoseok returns to Songju and sends a message to the group chat asking them how they are and telling them he’s back. Hoseok thinks of the day he left Songju and how his ankle isn't the only thing that has healed since then.
Hoseok calls Jimin to leave the lodge. Jimin takes a look at the mess they had left behind and starts walking outside. As he walks, Jimin realizes that the beach was the same one they had visited when in school. He calls out to Jungkook to share his discovery but Jungkook was already sprinting ahead. He thinks that Jungkook has grown up from the boy who used to lag behind and look up to others. He reaches the intersection- left will take him to the train station and right towards his house. Jimin realizes he has to confront his parents someday and own up to his lies and fears. He sees Yoongi exit for the left and turns right. Hoseok calls for him, but Jimin tells him that he is going home now.
The 7 of them ditch school to go to the beach. Jungkook feels his emotions rise up on seeing the ocean. They decide to walk towards the rock on the beach, 3.5 km away. The myth was that if people stood up on the rock and shouted their dream while facing the sea, it would come true. Yoongi is reluctant to go but Taehyung starts walking ahead.Jungkook recalls an earlier day when he had asked the others about their dreams. He wonders why if none of them had any dream as such, were they walking so far in the heat towards this rock.
As they walk, Jungkook gets scolded by Yoongi for the marks on his fingers. Yoongi tries to keep up a conversation by asking for Jungkook’s dream. Jungkook instead asks the meaning of a dream. Yoongi and Jungkook bond over this conversation. Jungkook looks at the marks on his fingers and remembers all the times he cut himself with a knife. Jungkook mentions how cutting himself helped him feel more awake, especially when he felt hollow.
The 7 of them reach a place with a lot of pebbles scattered around, wondering where the rock had gone. They give up searching further, and later find out that the rock had been obliterated because a high end-resort was going to be constructed at the beach. The rock would have obstructed the view from the first and second floor. They look around to find yellow bands and excavator machines, signifying development. They try to cheer each other up by saying positive things like the rock wasn’t real anyway, but all of them are disappointed. Jungkook sees Yoongi trying to bite his nails, and shouts to stop him, but the drilling noise in the background interferes. As the drilling noise continues, Jungkook asks Yoongi , “ Do you want to give up on this world too?”. They shout at each other but can't hear. Taking light of this situation all 7 of them scream their dreams into the sea, competing with the drilling noise.
The noise ends abruptly, leaving them in silence, with Jin’s “Please!” being heard loud and clearly. They decide to commemorate the day by taking a photo against the beach. Jungkook asks Jin for the photo, and Jin hands him over by scribbling the date on the back. Seokjin assures Jungkook that the dream he yelled out will come true.Jungkook asks him if he knows what it is, but only gets a tap on his shoulder as they walk ahead.
