Nanami, the ace of the track and field club, was a sprinter with the potential to compete nationally. However, she suffers a leg injury just before the competition. Seto, the male manager who has experienced setbacks himself, now supports her. Will she be able to compete in time…? During her grueling rehabilitation at the gym, school gymnasium, and swimming pool, Seto gives her intimate one-on-one massages, and the long hours they spend alone together make Nanami's boyfriend, Takizawa, suspect she is cheating and forces himself on her, forcing sex upon her… Takizawa seems only interested in sex, while Seto gently cares for her both physically and emotionally. The heat is transmitted through the touch of their skin. As if to fill the unspoken anxiety, their relationship goes beyond mere support and transforms into a passionate love affair where they intensely desire each other's hearts and bodies.
