A summer vacation on Jeju Island was supposed to be simple - sun, saltwater, and the same careful dance Minho (OC) and ITZY’s Yeji have maintained for years. Instead, their FWB dynamic gets pulled into the chaos of her group vacation, dragging up old memories, buried wants, and a version of each other neither has ever really let go of. What begins as sex quickly turns deeper, messier, and harder to name.

You're an overworked, underpaid, unappreciated intern at Aespa Group, one of Seoul's top women's fashion companies. On the busiest time of the year, you learn from your fellow intern Ningning that the Chairman's daughter, Winter, is returning from her overseas studies, and she's ready to making your life exponentially harder than it already is.

Holiday chaos erupts when Winter's toxic ex returns to the company, pushing the intern and Ningning to form a risky alliance for revenge. Amidst gift exchanges and gala preparations, a surveillance mission reveals shocking secrets that shatter the intern's view of his boss.

At the New Year's Eve gala, the intern attends as a "human shield" for Karina, only to be pulled into a high-stakes heist to recover blackmail material. Trapped in a hotel suite, he and Ningning must execute their plan while witnessing a private moment that changes everything.

A dangerous elevator encounter with a coworker leaves the intern vulnerable to blackmail, just as a kind new executive arrives and stirs up office politics. Jealousy flares when Winter notices his growing bond with her rival cousin, leading to a punishment that blurs professional lines.
