The tab was made by using a synthesizer and a guitar.
I do not read Korean so some chords may be misplaced but the rhythm/beat is the same throughout the whole song
so it is easy to follow.
For guitar I recommend playing:
Dm 5th fret
F 8th fret
Bb 6th fret
C 3rd fret
If a chord is in parentheses then it is optional or to maintain the rhythm.
