[All] Best day ever~! It's been 5 years but I still like this song ㅎㅎ

Release date 2018.12.13

I think it's a good song because it shows NCT's SM identity.

This song is also really oldㅠㅠ

If you look at it, it's an old song, but I think the songs that I listen to consistently are good songs~~

I hope there will be more long-running songs like this in the futureㅎㅎ
