The video starts with a footage of Kang Daniel's pre-debut interview from last year. Kang Daniel, a 2-year trainee at the time, explains why he started dreaming of becoming an idol star.
Then his journey on 'Produce 101' season 2 flashes by, leading up to the present as a member of the top boy group Wanna One.
'Produce 48' states the immense success of Wanna One was possible due to the 'Nation's Producers', and asks for them to cheer on for the trainees' dreams once again.
