This song still makes me feel so warm and fuzzy.
This was TVXQ's debut track and marked the return of boy bands, and particularly this boy band that changed Kpop history.
This is the original, and literally everyone can recognize it by just the first few notes.
Just listen to how loud the crowd is when they realize what song it is!
Jonghyun & Key
And of course SM has to rep their sunbaes ;)
And Chen has to go and make it all emotional lol
Who else loves this song!?
