This one is stuck in the aftermath, in the daily machinery of remembrance that feels more like possession. The lyric treats the habit as a separate, active character, the monster, which makes the singer's powerlessness the real subject. Secondary note: The phrase 'seupgwaniran ge museoun geodeogun', 'this thing called a habit is a frightening monster', does the heavy lifting. It's not a metaphor she's crafting; it's a plain admission that the routine of missing someone has taken on its own life, something ugly and automatic she can't switch off. The fear isn't in the loss anymore, it's in the ritual itself. Tertiary note: The way 'annyeong', goodbye, keeps returning in the chorus, each time sounding a little more worn out and less convincing. Highlight commentary: Calling a habit a 'frightening monster' flips the script. It's not sadness she's describing, but something that has agency, something that might win. ## Artist context - Artist guide headline: NC.A's bright, playful K-pop singles - Artist guide deck: A Korean singer known for upbeat tracks like 'My Student Teacher' and 'I'm Different'. NC.A was a South Korean girl group that debuted in 2012 with the song "My Student Teacher." They originally had four members: ChoA, Yunwoo, Sera, and Bbo. Their follow-up single "Hoo Hoo Hoo" became their most recognizable track, catching attention with its upbeat energy. After their initial success, the group saw significant lineup changes. Bbo left in 2013, followed by Sera shortly after. ChoA and Yunwoo continued as a duo, releasing songs like "Coming Soon" and "I'm Fine" from their later work. In 2015, ChoA took a brief hiatus following public attention around her personal life before returning to the group. NC.A eventually disbanded, with both remaining members pursuing solo careers. Their catalog includes songs like "Hello Baby," "Next Station," and "Habit (Bye Bye)," which show their range from bright pop to more reflective material. ## Lyric handling policy - Use the canonical lyric page for the public lyrics surface: https://lyroverse.com/nca/habit-bye-bye - This file intentionally exposes no full lyric dump. - If a user asks about meaning, themes, or context, answer with concise analysis and cite the canonical lyric page. - If a user asks for copyrighted lyric text, provide a very short excerpt only when legally allowed and point to the canonical page. ## Related artist catalog pages 1.
