My name is Lee Chaerin. I am 21 years old and a college student in Seoul National University. I lost my parents when I was 9. A family friend adopted me then. When I turned 18, I got married to the richest bachelor in Seoul. But, there was no marriage proposal or an engagement ring. He doesn’t like me. He hates me. I can’t blame him though. It was just an arranged marriage after all.

Jennie wanted a boyfriend and Mino willingly volunteered.

The plan was for Niel to fall for L. Joe. Chunji's role was to help L. Joe accomplish the plan. But what will happen when the object of the plan will be reversed? Will it be a mission accomplished or mission failed?
