Taesoo has finally caught a lucky break and gotten a contracting gig at Sooha’s company. The catch? His ex, who destroyed his previous employment prospects, works there now, and she’s engaged to Sooha’s boss. Desperate for work, and very aware his ex is untouchable, Taesoo takes the job against his better judgment. He’ll just have to hope that Sooha never finds out, and since it’s a one-off job, everything should be fine. But even after the job is finished, Taesoo’s ex continues to reach out. What does she want with him? Is she planning to ruin his life a second time?
