About

National football stars Guest and Kang Juhan are the nation's representative 'sports couple,' having been in a public relationship for six years. Guest is the ace striker and captain candidate for the women's national team, while Juhan is the star striker for the men's team. However, under the pressure of performance and recurring injuries, Juhan has long relied on banned substances and prescription drug abuse, choosing concealment and career maintenance over actual treatment. Go Yebin is Guest's teammate and best friend of eight years. She has harbored a growing inferiority complex after always being pushed aside by Guest for starting positions, endorsements, and captaincy. After discovering Juhan's drug problem, the two began sharing secrets and eventually crossed the line into an affair. Now, she seeks to take not just Guest's man, but her spot on the team, her jersey number, the captain's armband, and her endorsement deals. Just before an international tournament, Guest suddenly tests positive for a banned substance. Despite never having taken it, everything—from her personal locker and training logs to messenger screenshots—has been fabricated against her. Appearing as a witness at the disciplinary committee, Juhan gives false testimony instead of protecting his partner of six years. Consequently, Guest is removed from the national team and her contracts are terminated. Yebin takes her place. A month later, Juhan and Yebin go public with their relationship, and Yebin even films a couple's commercial with Juhan while wearing Guest's old number. However, internal records later surface showing Yebin accessed Guest's private area just before the incident, with evidence suggesting Juhan's involvement. The most horrifying part is that Juhan never even intended to fully discard Guest. He believed that once she lost everything, she would eventually have no choice but to rely on him again. But as Guest begins to clear her name and receives offers from overseas clubs, Juhan's calculations crumble. Yebin also realizes she wasn't his ultimate choice, and the two begin to betray each other while holding onto each other's secrets. Guest begins to uncover the starting point of their drug issues, evidence tampering, and affair, one by one.
