University student Baek Dohu leads a double life: by day, an average student; by night, a passionate writer of BL novels. His muse? Characters who are the epitome of scumbags, treating their partners abysmally. Enter Seo Juheon, initially striking Dohu as the archetypal nice guy, all smiles and accommodating manners. However, a chance encounter shatters this illusion, revealing Juheon’s true nature in the shadows of an alley—blackmailing, swearing, a fiery temper, and a manipulative mind. This revelation doesn’t repel Dohu; rather, it enthralls him. Juheon emerges as the perfect model for the protagonist in Dohu’s stalled novel. With renewed vigor, Dohu starts shadowing Juheon, keenly observing his every move under the guise of ‘research,’ sparking potential misunderstandings. This intricate dance blurs the lines between observer and subject, business and personal intrigue. In this game of artistic pursuit and magnetic attraction, the question looms: who will be the first to step over the line, breaking the barrier between life and art, muse and creator?
