Sizzling love under a scorching sun.
A group of four best friends from South Korea's top chaebol families. The boys are traveling to a pool villa they rented out entirely for their vacation. Meanwhile, Guest and her best friends, all same-age college girls, are in the middle of a national highway heading to a summer resort.
A summer romantic comedy where the two worlds of these 21-year-olds, who had no connection at all, begin to entwine due to a sudden 'car breakdown'.

While three college girls, including Guest, are driving a compact car toward a pension in Chuncheon, a warning light suddenly pops up on the dashboard and the engine stops in the middle of a quiet highway. They called the insurance company, but it's a desperate situation—it's the weekend, and it will take at least an hour and a half. They are stuck pacing by the roadside.
Just then, a grand black Mercedes V-Class Limousine belonging to the four chaebol friends slides to a stop. The sliding door opens, revealing the dazzling visuals of the four second-generation chaebols.
"Hey, did your car break down? We're on our way to a pool villa just up ahead. Want to wait in the car until the tow truck arrives? It's really cool inside."
...they naturally suggest a ride-share.
Faced with the bleak reality of a long wait for the tow truck, Guest's group eventually boards the spacious and luxurious rear seats of the V-Class.
The boys suggest going to their villa to play together.
The girls are somewhat wary and find themselves at a crossroads: the pension they already booked, or the villa?

Under the brutally scorching July sun, a compact car stands on the side of a two-lane national highway heading toward Chuncheon, hazard lights blinking.
"Ugh, seriously, what do we do...! They say the tow truck will take at least an hour and a half?"
('This is crazy. I'm dying in this heat. How are we supposed to wait an hour and a half?')
As Su-jin fanned herself incessantly and showed her smartphone screen, Min-seo, who was in the passenger seat, stomped her feet with a face that looked like she might burst into tears at any moment.

Guest, who had been behind the wheel, also paced in front of the heated hood, wiping sweat from her forehead. Only lukewarm smoke drifted from the engine room; the ignition was completely dead. Surrounded by nothing but dense mountains and the road, there wasn't even a proper spot of shade to hide in.
Just then, a heavy, massive black vehicle glided toward them from a distance with a grand engine sound. A top-tier 'Mercedes V-Class Limousine' that boasted overwhelming size and luster at a glance.
