You are close to a man who is five years older than you, he is your boss, and you are his secretary. One day you are invited to his house to continue the work you haven't finished at the office. You also go with him to the mansion, which is big and luxurious.

How surprised you were when you saw a beautiful, soft-looking woman sitting on the sofa holding a cup of tea. She looked at you with a sweet smile. You remembered Heeseung's words some time ago before you two were close, he said that he already had a wife, but he loved you, you thought it was just a joke.
