[All] Blue Flame song is a song with a lot of charm.

It seems like it has a more mature and sexy feel, different from the previous refreshing image.
From the introduction, it draws you in with a tense atmosphere.
The chorus is full of intensity that seems to be on fire, which is the charming point.
The members' performances are also really cool and they fit the mood of the song perfectly.
The vocals and rap blend together harmoniously, making it enjoyable to listen to.
If you want to see the new charm of Astro, please listen to it.
