Bài hát: The Words In My Heart (I'm Not A Robot OST) - Kim Yeon Ji

Na myeochireul alkoman isseo
Gaseumi neoro beokchaseo
Sum swineun ge
Jamdeuneun ge himi deureo

Ne yeopindedo
Maeumeun ne yeope gal su eopseo
Hangsang neol geuriwoman hae
Geuriumeun
Oneuldo nunmuri dwaesseo

Malhaebogo sipeo
Na bulleobogo sipeo
Neul ipsul mate meogeumgo
Doenoego doenoeneun
Maeumui mal

Amuri oechyeobwado
Neoegen deulliji anna bwa
Maeil sogeuroman
Nunbicheuroman
Malhaeya haesseotdeon
Neol hyanghan sarangui mariya

Gin haruga doeeobeoryeosseo
Na neoreul gidarineun ge
Sum swideusi
Dangyeonhan iri doen geoya

Malhaebogo sipeo
Na bulleobogo sipeo
Neul ipsul mate kkeonaetda
Gamchugo gamchuneun

Amuri oechyeobwado
Nae mami boiji anna bwa
Balgeun eolgul dwiro

Nunmureul jiugo jiwoya haenneunji moreul geoya
