Cigarettes and Soap Bubbles
Artist: Lovely Summer Chan
あなたは煙草 私はシャボン | Anata wa Tabako Watashi wa Shabon
Unique wah wah reverb guitar tone and ambiance. Lyrics are about her being a soap bubble and him being a cigarette, she's easily broken and cigarettes are addicting and comforting, but ultimately bad for your health. I think it's an accurate metaphor for the relations of people.
I remember Lauren had compared people to a wick, I suppose it's kind of similar.
