Hyperventilation

Lee Myeongyi has lived with a collapsed lung since birth, often drawing unwanted attention at school due to his hyperventilating episodes and exemptions from physical education. Despite this, Han Seonho, the class president, has shown him kindness, leaving a lasting impression on Myeongyi. Nine years later, Myeongyi attends his high school reunion, hoping to reconnect with Seonho, but is disappointed to see him married with a gold wedding ring. Their encounter outside the reunion, however, unexpectedly sparks a secret relationship between the two men.
