Rollercoaster Romance

Rollercoaster Romance follows the chaotic and heartwarming life of Lee Da-in, a dedicated theme park designer who finds her professional and personal life colliding when she is tasked with renovating the park's oldest, most iconic attraction. As she works to modernize the ride, she is forced to collaborate with Kang Min-ho, a cynical and perfectionist engineer who believes that some things are better left untouched by sentimentality. As the project progresses, the two find themselves navigating a series of unexpected emotional highs and lows that mirror the very attraction they are building. Amidst corporate sabotage, family secrets, and the pressure of a looming grand reopening, Da-in and Min-ho must decide if their growing connection is just a fleeting thrill or a foundation strong enough to last long after the park lights dim.
