Lyric

The song was created when Eco Skinny, who has suffered from asthma since childhood, was using a spray medicine called Aerosphere, which is prescribed when his cough symptoms become severe. He thought it would be nice if he could be an Aerosphere for someone when they are physically and mentally exhausted, can't sleep, or have uncontrollable anxiety.

The lyrics are neither whiny nor assertive, but they touch on the contradictions and powerlessness that lie at the root of human beings.
On top of that, the gap between his singing voice, which sounds like he is running towards a light seen from afar, and the rock-like sound creates a gap, and it is by no means all pretty. However, it is packed with his unique music that gives strength.
Asthma is generally an incurable disease that can only be accepted, but with Aerosphere, you can temporarily return to normal. From the outside, it may seem like he is just ignoring it, but perhaps everyone spends their days like that.

it's a song full of humanity that mysteriously gives you strength.
