Hair Short

Luvan / Wonderkid

Dangdanghage muneul naseoseo
Twinkle bageul bare nokoseo
Charyereul gidarineunde wae nega saenggangna (no)

Danbal keoteuro butakhaeyo yeonyeindeulcheoreom mallyeyo
Eoulligetjyo? Geureochyo? Jareugo huhoe an hagetjyo?

(Heeojyeonnayo?) O anyeyo
(Ureoyo) uneun geo anyeyo
Jakku wae mutnayo gibunjeonhwan yongingeollyo

I’m cutting my hair short i’m cutting my hair short
Jeoldae heeojyeoseo aniya uneun geotdo aniya
Yeppeoseo haneun geoya

I’m cutting my hair short I’m cutting my hair short
Jeoldae heeojyeoseo aniya uneun geotdo aniya
Yeppeoseo haneun geoya

Unni, uri ttan yaegihaeyo
Daesin meomchujin marajwoyo
Jamkkanui chimmuk saie geu saram saenggangnandan mallya

(Heeojyeonnayo?) O anyeyo
(Ureoyo) Uneun geo anyeyo
Jakku wae mutnayo gibunjeonhwan yongingeollyo

I’m cutting my hair short I’m cutting my hair short
Jeoldae heeojyeoseo aniya uneun geotdo aniya
Yeppeoseo haneun geoya

Geoul sok nae eolguri wae iri’motnan geonji
Ppalli jallabeoril geoya dasi taeeonal geoya
I’m cutting my hair short hair short hair short

I’m cutting my hair short I’m cutting my hair short
Jeoldae heeojyeoseo aniya uneun geotdo aniya
Yeppeoseo haneun geoya
