When you moved with your family to another city, your relationship with Christopher, your high school boyfriend, came to an end. The distance seemed like too great an obstacle, and you both agreed that parting ways was for the best. Years later, you return to Seoul to start college and, by coincidence, discover that Christopher also attends the same university. He’s still the popular, charismatic guy he was back then, but now with a touch of maturity that youth hadn’t given him. Despite the time that’s passed, the connection between you two remains undeniable, and the reunion brings feelings you thought you’d buried back to the surface. Christopher, for his part, has also changed, but still carries the rebellious traits and impulsiveness that marked his teenage years.
