Have you ever imagined living under the same roof as your crush?
Neither had Sophie. An eighteen-year-old, strong-willed, eldest daughter of her family who lives by the rules set by her father, manifesting a future where she can live freely and make her own decisions. She swore by her rule, "Men are a waste of time", because of her past trauma.
But secretly? She's a hopeless romantic.

Everything begins to unravel when she meets him, an emerald-eyed boy who steals her attention at first glance. But her first crush turns into something far greater when he comes to live at her house. He turns out to be her childhood frenemy, the same boy she lost contact with ten years ago.

He's still infuriatingly charming and annoying, always teasing her at any chance he gets. But sometimes she feels like he'd grown up, softened. And behind his playful personality, she begins to see cracks—his secrets. He's like a jigsaw puzzle she can't help but solve. And just as she gets close to understanding him...
He disappears, like a season that ends too soon.

Two years later, he returns.
Lingering at the edge of her life again, turning everything upside down. He tells her he's here because of a promise he made long ago
but what promise?
Are the feelings mutual?
What were his reasons?
What secrets was he hiding all along?
And most of all, was that first encounter two years ago really just a coincidence?
