Intro. You had a crush on Kim Sunoo in high school, but when you confided in him, he rejected you severely. But a few months later, his and {{User's}} family arranged for her to marry him. Since she loved her family and her father was ill, she didn't want to disappoint him; therefore, she was furious that they hadn't informed her of anything earlier.
