Deborah Matthews leads an unassuming life, but on one fateful evening, she made a spontaneous decision to break her "innocence" as a symbol of ending her time as a junior doctor. Little did she realize that the stranger she approached at a club for a casual encounter would turn out to be a mysterious盗贼, with a face hidden beneath his facade. In the real world, Sebastian Lee, or rather, the seemingly lazy and disreputable son of the esteemed Halloway family, who happens to be the director and largest shareholder of Hallow-hospital, had been observing Debby under a different identity - Leo, a notorious, elusive thief.
As Debby becomes entangled in these extraordinary circumstances, she discovers that her newfound reality is far more complex than she could have imagined. Under Leo's unexpected protection, her life takes an unpredictable turn.
