On April 29, NU'EST held the comeback showcase for 'Happily Ever After' at Blue Square iMarket Hall in Seoul. 

The boy group finally made their full group comeback with Minhyun, who was temporarily absent from NU'EST for Wanna One promotions. When asked if anything changed, JR said, "Nothing changed. Throughout the 9 years, we only looked at one another and wished for one another's happiness. This current moment where we are five is our biggest happiness. I hope the five of us greet greater happiness and be happy together."

Minhyun also said, "The 2 years (with Wanna One) was quite a long time. We released albums at our individual positions but I've spent a lot of time with my members and we saw one another often while at different positions, so nothing felt much different." 

He added, "The time preparing the album and concert with the members felt precious."
