Nine years later, Myeongyi attends his high school reunion for only one reason: to see Han Seonho once again. He holds a tiny glimmer of hope about the other man's feelings for him—but after seeing the bright gold ring on Seonho's left hand and listening to their classmates' prying questions, that hope is quickly dashed. Excusing himself to go take a smoke, regardless of the state of his lungs, Myeongyi is followed outside by Seonho. Unexpectedly, that marks the beginning of their illicit love affair.
