Letra da Música: Be Happy - Kang Sung Hoon

Meil ni sengage haruga negen bujoghe
buduron ne mogsoriro dullyojwo (saranghandan)
gumari dudgo shiphojyo
gwichanha hajima yongwonhi nol saranghe

Nomu hengboghe handushiganun do nujodo gwenchanha
noege hangajiman buthaghe (onjena nul)
ne sengage hengboghagil
onuri jinago to neiri jinado yongwonhi

[Rap]
Noui sarange urin nomuna hengboghe
ibami dagadorog uri sarangui norerul hamkebulloyo
yongwonhi kunhgiji anhnun sarangui melodie
nomunado arumdaun sarangui hamoni
ibami kuthnado nesarang negyothe momulloyo
kuthiobjyo norul hyanghan nesarang
(yongwonhi nal iji anhgo saragagil)
nunbushige arumdaun dangshin
gubichuro pogunhage narul onajwo
(onuri jinago to neiri jinado yongwonhi)

Onjena hamke issoyo ibyori oji mothage
tatuthan gudehyangiga nemamul sarojabajyo
(nunbushige arumdaun dangshin nunbichuro pogunhage narul anajwo)
dalkhomhan ibmachum nege hejulleyo

Tonight na nunul toboni gudega bogoshiphojyo
jogumman gidaryojwoyo na jigum naragalkeyo
(nomunado bogoshiphun dangshin onjerado naui gyothe hamke issojwo)
nuji anhulkeyo jogumman do chamayo nesarang

[Rap]
Himdun haru haru na gudel sengaghamyo
kumul mugo inungol ne gyothe yongwonhi ne gyothe yongwomhi
saranghe imari daingol negyothe yongwonhi forever my love
