NCT Dream took their "No. 1" energy to the April 27th installment of 'Immortal Song'.

On part 2 of the 400th episode Japan special, NCT Dream performed for the first time on the competitive reality show with their cover of BoA's 2002 hit song "No. 1". The NCT unit expressed, "We practiced a lot for our first performance on 'Immortal Song'. Our labelmate EXO's Chen gave us advice in the practice room and told us to work hard and don't make mistakes."

NCT Dream pumped up the audience with their song, but in the end, it was Wanna One's Kim Jae Hwan who took the final win.
