Suzu, the ace of the track team, had always strictly trained her teammates, especially Nagi. But one day, alone together in the club room, Suzu suddenly changed her demeanor, warmly encouraging Nagi. Noticing Nagi was tensing her legs, Suzu began giving her a massage. Nagi felt as though the gap between her and her admired senior—once distant and unapproachable—was slowly closing. Then, without warning, Suzu suddenly kissed her. Feeling the soft warmth of another woman's lips for the first time, Nagi froze completely, unable to move, as if paralyzed.
