The music video released today captures Crush, deep in thought, anxiously pacing alone in a room. Later, Crush enjoys happy moments with his loved one, creating a pink-hued atmosphere. However, the mood shifts as Crush's expression turns somber, adding to the intrigue surrounding the music video.

"Ego" encapsulates the complexities of love, cleverly expressing the growing love as the word "Ego" repeats. The song is complemented by an upbeat rhythm and Crush's acapella, creating a charming mood.

Upon its release, the new album quickly dominated the Melon music chart HOT100, with all 19 tracks securing spots. Particularly, the quadruple title tracks, "Hmm-cheat" and "Ego," continue to climb the charts, maintaining their upward trajectory.
