Yellow Line is a tender and refreshingly honest Korean BL that unfolds within the vibrant halls of a university campus. Jae-won, a straightforward and warm-hearted student, finds his daily routine disrupted when he's assigned as a peer supporter for the enigmatic and cold-leaning transfer student, Seo-jun. Seo-jun is sensitive and guarded, carrying unseen burdens behind his icy exterior. As Jae-won patiently chips away at those walls through small gestures of kindness, an unexpected bond blossoms into a sweet, slow-burn romance. This series beautifully explores the push-and-pull of two young men navigating first love, friendship, and the courage it takes to be vulnerable. With its authentic university backdrop, relatable supporting characters, and a focus on emotional intimacy over dramatics, Yellow Line delivers a quiet but powerful story about connection and self-acceptance that will leave you smiling.
