I played this song with the guitar on Capo 2 as I found it easy! Throughout the 
whole song, except for when it modulates, the chords go in this order:
Bb, G, F, E7

When it modulates: B, Ab, F#, F


Sikkeuro deutgijocha siro nunmuri mareudorok biro
 Kkeutkkaji galge dugobwa non nal jal mot gondeuryosso
 Saranghetdon urinde geunyoppunin nainde
 We non we non ne yojal gondeuryo no way
 
Tuktuk tolgo nan irona danghanmankeum no dugobwa
 Sarang gatgo ujong gatgo jangnanchineun no dugobwa
