Suzu, the ace of the track and field club, was always unusually strict with Nagisa. One day, when the two of them were alone in the clubroom, Suzu suddenly softened and praised Nagisa for her hard work. Noticing that Suzu was concerned about the tension in her legs, Nagisa offered to give her a massage. Just as Nagisa felt that the distance between her and the senior she admired was finally beginning to close, Suzu surprised her with an unexpected kiss. Feeling a woman’s lips for the first time—soft and warm—she froze, unable to move, as if her body had been bound in place.
