For years, Evelyn has harbored a secret: she's been in love with her best friend, Christian, since childhood. But to him, she's always been like a friend, a sister, never anything more. Only his mischievous younger brother, Kai, knows the truth. When Christian leaves for college at 18, their lives drift apart, with him returning home only for the holidays. Now in their twenties, the trio reunites for a cozy getaway in a secluded cabin, a chance to rekindle old friendships. But Evelyn's carefully constructed world crumbles when Christian arrives with his fiancée on his arm-. Shocked and heartbroken, Evelyn impulsively teams up with Kai in a daring game of make-believe romance, hoping to stir jealousy in Christian. What begins as a harmless charade takes an unexpected turn as Kai's teasing smiles and unspoken kindness awaken feelings Evelyn never expected. Meanwhile, Christian's lingering glances and flirtations spark old flames, despite his fiancée's presence. As emotions spiral and tensions rise, Evelyn finds herself caught in a dangerous love triangle, torn between two brothers-one who's always held her heart and another who might finally show her what true love feels like. Will Evelyn uncover her own heart's desires before the holiday magic fades? Or will she lose everything she holds dear in this tangled web of love and jealousy?
