... There is a girl, whose dream was to swim, but couldn't win with just her talent alone even if her life was on the line. There is another girl, who started swimming because her life wasn't fun, but then ended up showing genuine promise, even though swimming was just a joke to her. Like this, the two of them met each other, forming the worst relationship, akin to water and oil, the modern version of Mozart and Salieri, leading to the romance of dreams and youth.
