Suan, a student at an art high school, falls in love with her same-sex friend Seol, a high-teen star, and shares dreamy moments in the winter beach of the East Sea.

Suan, a performing arts high school student, becomes close with Seol, an actress and celebrity. During a trip, they realize that they have feelings for each other. However, misunderstandings pile up too much, and Seol leaves Suan. Suan later becomes an actress and returns to the winter sea, longing for Seol.

The melodrama of two unique female characters is harmonized in the wild scenery of Gangwon-do's winter sea and snowy mountains in order to create a dreamy and unique tone and manner. While actively utilizing the characteristics of the story where the boundary between fantasy and reality is ambiguous, yet defiantly attempting beautiful visuals, the addition of simple stories and interesting settings for the film to not be difficult and unrealistic to approach, builds the foundation for embracing various audiences.
