Jiran, a self-proclaimed art student with both talent and pride, packs her paintbrush and heads to the beach to escape the shock of Professor Baek's harsh critique of her work and the misunderstandings arising from a chance encounter with her friend Eunsook's boyfriend, Junseok. While capturing the freedom of the sea on canvas, Jiran meets Hyunwoo, who is in love with Soyoung, who is dying of an incurable disease. Seeking to help, Jiran offers Hyunwoo a hefty fee to pose nude. Hyunwoo, mindful of Soyoung, accepts Jiran's offer.
