To the outside world, Jihun and Seonjae seem like ordinary classmates, but there is something unspoken binding them that no one else can see. Jihun follows Seonjae’s every word without question, as if under some quiet, unbreakable command. Watching from the sidelines is Ki-wung, who grows increasingly disturbed by the dynamic and tries to pull Jihun out of Seonjae’s shadow. As the line between control and devotion begins to blur, Jihun must decide whether he can truly break free from Seonjae’s grip or if he has already surrendered to it completely.
