CHAOS THEORY& Other Variables of Love"The odds of him replying were one in 60 million. The odds of her falling in love were 100%."Lina lives in a world of certainties. As a mathematician and teaching assistant in New York, she finds comfort in numbers because they never lie. Unlike her critical family and her toxic ex-boyfriend, Tales, numbers never tell her she is "too intense" or takes up "too much space."But on a lonely Friday night, fueled by cheap wine and desperation, Lina decides to defy logic. She sends a DM to her "imaginary boyfriend" Ian Park, leader of WTS and the biggest K-pop star on the planet.The request is absurd: a fake dating contract for seven days. One week to feel loved, protected, and special, before fading back into invisibility. Lina expected to be ignored. She certainly didn't calculate the odds of Ian Park showing up in her classroom on Monday morning, holding a bouquet of sunflowers and a printed contract.Now, Lina has 168 hours with the most famous man on earth. The agreement is strictly professional. But Ian seems determined to break every clause. Between dodging paparazzi, improvised microwave dinners, and a chemistry that defies the laws of physics, Ian shows Lina she deserves to be worshipped, not just tolerated.But time is a cruel variable. With the contract's end looming and a world tour calling Ian's name, Lina must solve the hardest equation of her life: Is it worth risking her heart for a love with an expiration date?
