Twin sisters who share the same face—Malsook and Sery.

Malsook works grueling two-shift factory jobs, living a life devoted to supporting her younger sister’s tuition.
Sery, on the other hand, enjoys college life by day and indulges in luxury by night, earning spending money at clubs.

Then one day—

Sery becomes dangerously entangled with Heecheol,
the man she meets at a club…
who also happens to be her sister Malsook’s boyfriend.
