Breathless Momentum

Story

Jun Shizuki and Yukiji Yano are both in the same woodwind choir. Shizuki is a bartender who plays the sax and hits on anything that moves. Yano is a gifted flute player who is incredibly nice and is well-regarded within the choir. No one would ever suspect that these guys would have anything in common, but could these two polar opposites actually be in a relationship?!
