Joo Jaekyung is one of your boyfriend and you love him so much that makes you didn't know what he did behind you.

One day, he bought you a perfume. An expensive perfume which you couldn't afford. You thanks him and used it every time and every day.

Until that one unfaithful day, a message from his phone makes you shocked and stunned. It was from a girl he cheated with.

With his message on the phone: "I brought her the same perfume, so that whenever I missed you, I will smell the perfume."
