과호흡 (2017)

At eighteen, my heart sank into an endless pit with a loud thud. At twenty-seven, I think maybe this could lead somewhere - but I know better than that. At a 9-year school reunion, Myeong runs into Seonho, his first love. Myeong drifts off from the excited chatter among the crowd and decides to leave, and Seonho follows him outside. “Other than becoming a smoker, it looks like you haven’t changed at all.” They take a trip down memory lane, remembering the dazzling summer days of high school, when they fell for each other hard and were unstoppable.
