The spark in the cigarette butt fell in love with the filter at the end. Spark wanted to get closer to the filter, so it glowed and heated desperately to shorten the distance between them. But when it got closer and closer to the filter, it found that the filter was damaged by the heat it brought. As a result, the spark gradually cooled and eventually went out, and all the past had long since become smoke and clouds behind it. Maybe it's best to keep a cigarette distance from each other at the beginning, because one of them is a spark and the other is a filter.
