이유 없이 웃음이 나와
분명히 난 이때가 싫었는데
한달 내내 빛나는 거리와
캐롤들이 다 이해가 안 갔는데

누구보다
오늘을 기다리던 너와
만나니까
이상해 이젠 내 맘이

I think I'm fallin' in love with Christmas
이제야 알 것 같아
왜 그리 사람들이
이 날에 설레고, 이 날을 기다렸는지?
Fallin' in love with Christmas
사랑이 넘치니까
따스한 겨울이란
마법에 빠지는 날
Lovin' the Christmas

언제보다
오늘 우울해지던 나야
근데 뭐야?
이상해 이젠 내 맘이

I think I'm fallin' in love with Christmas
이제야 알 것 같아
왜 그리 사람들이
이 날에 설레고, 이 날을 기다렸는지?
Fallin' in love with Christmas
사랑이 넘치니까
따스한 겨울이란
마법에 빠지는 날
Lovin' the Christmas

It's full of wonders
선물 같은 시간
설렘만 가득한

Fallin' in love with Christmas
이제야 알 것 같아
왜 그리 사람들이
이 날에 설레고, 이 날을 기다렸는지?
Fallin' in love with Christmas
사랑이 넘치니까
따스한 겨울이란
마법에 빠지는 날
Lovin' the Christmas

[English translation:]

A smile slips out for no reason
I was sure I hated this time of year
The streets that kept glowing all month
And all those carols I could never quite understand

Meeting you
Who looked forward to today
More than anyone
It feels strange, now my heart starts to

I think I'm fallin' in love with Christmas
I feel like I finally get it now
Why people got so excited for this day
Why they'd been waiting for it
Fallin' in love with Christmas
Because love is overflowing
A day you fall under
The magic of a warm winter
Lovin' the Christmas

More than any other time
It's me, the one who was more down today
But what is this?
It feels strange, now my heart starts to

I think I'm fallin' in love with Christmas
I feel like I finally get it now
Why people got so excited for this day
Why they'd been waiting for it
Fallin' in love with Christmas
Because love is overflowing
A day you fall under
The magic of a warm winter
Lovin' the Christmas

It's full of wonders
Time that feels like a gift
Filled only with excitement

Fallin' in love with Christmas
I feel like I finally get it now
Why people got so excited for this day
Why they'd been waiting for it
Fallin' in love with Christmas
Because love is overflowing
A day you fall under
The magic of a warm winter
Lovin' the Christmas
