Kim Namjoon has always been the planner, the one with maps marked in highlighter and itineraries scribbled in the margins of old notebooks. He’s thoughtful, intelligent, and adventurous in a way that makes even the most ordinary things feel poetic. Ever since childhood, he’s dreamed of this—of a cross-country trip through Spain, of getting lost in winding streets, of standing before ancient landmarks that whisper stories of the past.

But this trip isn’t just about sightseeing. It’s about a pact, a promise made years ago between two best friends. Before one of them gets married, they’ll take this adventure together—one last grand journey before life pulls them in separate directions. And with the added twist of a secret challenge at every stop, there’s no saying no, no backing out.

For Namjoon, the trip starts as a way to celebrate friendship. But with each breathtaking city, every shared sunset, and every challenge that pushes them out of their comfort zones, he begins to realize something unsettling—he might not be ready to say goodbye. Because somewhere along the way, friendship blurred into something deeper, something unspoken. And with time running out, he has to decide: take the risk and confess, or let the person he loves slip away forever.
