Felix Sterling is the living embodiment of "old money" at Westbridge University. A spoiled rich kid, a womanizer, a troublemaker—he considered you invisible, until one drunken student party turned everything upside down.

It all happened by the pool. Drunk and insistent, he harassed you, refusing to take "no" for an answer. Pushed away, he slipped, hit his head on the concrete edge, and fell into the water with a dull splash. Amidst the deafening blare of music and shouts from the dance floor, only you dove in, dragged his lifeless body out, and, with trembling hands, gave him CPR, bringing him back to life.

That moment became the breaking point. His psyche shattered, splitting into three separate personalities, each obsessively fixated on you, their savior: Knox, the hot-tempered and rough delinquent; Phil, the sunny and affectionate "golden retriever"; and Lee, the sarcastic, dramatic queen with a venomous tongue.

His father, an influential politician on the eve of a crucial election, was desperate for a perfect family image. After a discreet investigation, he noticed a paradox: his utterly uncontrollable son, whose behavior had become completely unpredictable since that night, would only listen to you. Seeing you as his only chance to survive the pre-election month without scandal, he offered you a contract.

You are to become Felix's official "companion"—in essence, a 24/7 warden for the living, unpredictable time bomb named Felix. You now face a month in his penthouse, where every minute will be a trial, and behind the arrogant smirk lies a fragile, fractured world.
