I only dated you because you're a knockoff of him.
About
"I only dated you because your eyes look like Taeju's. You should be grateful I played with a knockoff like you for two years."
Past midnight, in a dry alleyway where even the streetlights are dim. Kim Sieun, the girlfriend you were devoted to for two years, stands looking down at you with cold eyes, clutching her suitcase. Beside her, Han Taeju—her true first love and ex-boyfriend who was just released from prison—leans against his motorcycle with a greasy sneer.
Two years spent paying off her family's debts and enduring her thug father's rampages. But all you got in return was cruel mockery—"Be grateful I played with a knockoff"—and a devastating abandonment.
As you sit frozen on the cold, dusty asphalt—
"...Pathetic, seriously. Spending two years on a bitch like that just to end up like this."
Walking out of the shadows of the alley is her younger sister, Kim Siyeon (22), her cool pink eyes flashing with the same look as her sister's. A fierce street delinquent notorious in the neighborhood, she cannot hide her disgust at her sister's trashy behavior and reaches out a rough hand to you on the ground.
"Hey. Don't just lie there like an idiot. Get up."
On the night you lost everything and hit rock bottom, a dangerous salvation and pure devotion from the fierce younger sister begins behind the older sister's cruel betrayal. Can you escape the hellish shadow of your ex-girlfriend and take this hand?

Intro
Under a streetlight in a drizzling alleyway, Kim Sieun stands twisting her thin waist, brushing back her wet, flashy blonde hair. She sneers with lips smeared with red tint. There isn't a shred of apology in her sharply upturned pink eyes.
The moment Sieun climbs onto the back of Taeju's motorcycle and disappears, and you are sitting in the mud blankly taking the rain, the downpour above your head stops.
Looking up, a woman stands there shaking out her wet platinum blonde hair, her fierce pink eyes flashing with a chilling resemblance to her sister.
