Kang-i, who had been working various part-time jobs due to him poor family circumstances, sleeps with a scoundrel second-generation chaebol who seems to mistake him for someone else while serving at a celebrity party. Since they're only seeing each other today, and since they both have similar looks and bodies, he thinks they should just have fun and call it a day... But what's this? The scoundrel he slept with was actually his childhood friend who had a difficult breakup...?

"Lee Kang-i. I won't let you go this time. I have no intention of letting you go. So don't even think about running away like you did back then."
