Ah, why does it have a cheerful yet honest atmosphere?

It feels like it relieves my stifled feelings.
Thanks to the exciting rhythm, I don't get bored listening to it at all.
DAY6's unique vocals are appealing.
If you listen to it repeatedly, the melody naturally becomes familiar.
It's a good song to listen to when you want to change your mood.
It's a song that would probably be even more exciting to hear live.
