The college contract||Kmj

Calista, a Greek girl with a painful past, was orphaned young and adopted by a powerful, famous Korean family-close friends of her late parents. They raised her as their own, shielding her with love, comfort, and status.
But not everything in her life was easy.
Especially him.
Since the day she moved to Korea, Calista had one constant rival-the infuriating, competitive, and dangerously charming son of another elite family. From test scores to taunts, they fought over everything. But after he left for college, he disappeared from her life... until tonight.
He is going to pay a visit to her house with his parents with a special deal.
A contract.
An arrangement.
A marriage neither of them chose.
What exactly is the "deal" their families are finalizing at night, behind closed doors?
Why them?
And what happens when years of rivalry, resentment-and maybe something more-begin to resurface?
