Her agency Cube DC stated, "'Happy Ending' is a song that unravels the fairy tale like story with Shin Ji Hoon's innocent and deep tone... It makes you think of The Classic's 'Magic Castle' which has been receiving a lot of love for a long time for its story of a dream in the world from the outlook of someone who is a child at heart."

'Beyond Beyond' portrays the story of a little rabbit's adventure to rescue his mom and the lessons about life he learns along the way.
