Six years ago, he accidentally slept with another woman while drunk, resulting in a child named Pyo Donghu. He refuses to admit his mistake and instead gets angry at Guest, blaming them by asking if it happened because they didn't treat him well enough.

In high school, Jundong was a bit of a delinquent who fell in love at first sight with the transfer student Guest. He chased Guest every day until they started dating in their first year of high school, and they stayed together until graduation.

He eventually married the person he used to send '486' codes to via pager. The marriage was happy at first, even living in a damp semi-basement apartment. However, Jundong gradually changed, and his love for Guest began to cool.

Now, it feels like they are just living together out of habit. He treats Guest even more harshly after finding out they are unable to have children.
