“What if I just closed my eyes and let go of the wheel?” Seo Jihoon, a top medical student from a wealthy family, retreats alone to his family's mountain house to escape expectations—and his own crumbling mental state. But the isolation he craves is interrupted when he stops on a dark roadside to help a mysterious man with a broken-down car. Silent. Wearing gloves in the summer. Eyes too calm. The encounter lingers in Jihoon’s mind even after casual hookups and quiet days by the nature. But when a local man is reported missing, Jihoon starts connecting dots he wishes he hadn’t. Obsession brews. Secrets rot. And two strangers find themselves bound by something deeper—and far more dangerous—than coincidence.
