Trivia, insights & behind the scenes
Child actors Yeo Jin-goo and Kim So-hyun became so iconic that fans petitioned for an entire drama just starring them—their chemistry reportedly made adult cast nervous.
The 'first love never dies' trope here escalates to pathological extremes, reflecting Korean melodrama's obsession with pure love corrupted by class violence—Soo-yeon's 'dirty' past makes her literally unmarriageable in the narrative's logic.
