by car, but as the two pass through a tunnel, Ji-min begins to feel uncomfortable. Seeing the arboretum sign ahead of them, Ji-min panics and rushes out of the car. Seok-jin is sent back once again to the start of the time loop. Exhausted over his successive failures, Seok-jin refuses to relive his life and save his friends, and he spends the time loop sulking inside his room. Unexpectedly, Tae-hyung visits Seok-jin on the next iteration, motivating Seok-jin to continue in the challenge of rescuing his friends and escaping the loop. Seok-jin proceeds to saving Nam-joon, Jung-kook, Ho-seok, Yoon-gi and Ji-min in the safest way possible.

He reveals he had also seen himself in his dreams but, once he wakes up, he is unable to recall what happened to him in the dream. As the two arrive at an apartment, both hear an angry voice seeming to come from Tae-hyung's dad. Sensing his father's tantrum, Tae-hyung rushes to the apartment with Seok-jin tailing behind him.
