Sand Castle

When Eun-Seong accidentally stumbles upon his crush, Ji-U, inside an empty lecture hall, the unexpected encounter reveals a private secret shared between them. Rather than driving them apart, this hidden truth draws the two young men into a closer, more intimate orbit. However, the dynamic quickly proves unbalanced. Ji-U shows no genuine interest in Eun-Seong as a person, viewing him instead as a convenient outlet to satisfy his own selfish desires. Exhausted by being treated as nothing more than a means to an end, Eun-Seong eventually reaches his breaking point and undergoes a profound change of heart, deciding to step back from the one-sided arrangement. Ironically, it is precisely at this moment of withdrawal that Ji-U begins to recognize his true feelings. For the first time, Ji-U starts treating Eun-Seong with genuine affection and warmth, completely reversing the emotional roles they once played. With their positions now entirely switched, the two boys find themselves navigating a complicated new reality. As the one who was once indifferent desperately seeks connection and the one who once longed for it pulls away, they must face a difficult question: can a relationship built on such uneven ground truly survive when the balance of power shifts so drastically?
