After failing at both love and work, Dokyung returns to the stillness of her hometown, Mooyung, where a chance encounter at her mother’s old corner store brings her face-to-face with Doh Joon, a top actor with eyes like midnight. What begins with a bold proposition soon turns into something far more complicated: a fleeting summer affair between a woman afraid to love again and a man who wants forever. As their days grow hotter and their nights more intimate, Dokyung clings to the idea that it’s just a season, just a moment. But Doh Joon is already dreaming of something that lingers long after summer ends.
