Four-Digit Memory

"The four-digit passcode I type every time I unlock my screen is still your birthday."
Even as time has passed since our breakup, my fingers automatically remember the digits. Although it could easily be changed at any moment, updating it feels like completely severing the remaining bond with you. Centered on the theme of "putting heart into the music rather than over-decorating it," this lingering heartbreak is sublimated into an emotional, chill electro-acoustic pop track.

To guarantee absolute originality and completely prevent any melodic overlap, the chorus adopts a "4-digit-tap-falling-pitch" melody structure-rhythmically tapping four identical staccato notes like entering a passcode before smoothly dropping in pitch at the end of every phrase. Driven by an urban sound that strips away unnecessary ornamentation, the production dramatically wraps around the bittersweet attachment and memories illuminated by the screen light.
