Lời bài hát Not Only Friends (Heartstrings OST)

Ca sĩ: Oh Won Bin
ijeneun huhoehaedo soyongeobtjyo ijewa butjabado soyongeobtjyo

dasineu n bureujido motagetjyo dasineun bulleoseodo andoegetjyo
jal ga maeume eomneun malman namgigo tteonagayo

# geujeo chinguroman aranna bwa geujeo ujeongira aranna bwa
itorok bogopeunde itorok dapdaphande nae mamdo babocheoreom sogigo
