Ji Yu is a lowly temp, the kind who gets bullied by her boss every day. Luckily, the department is getting a new boss returning from overseas, who is said to be beautiful and kind to her subordinates. But she didn’t expect that this new boss is actually an ex-girlfriend who has a grudge against her! Ji Yu was young and reckless in school, so when she fell in love with a timid junior girl, she harassed the younger girl with hugs and kisses even when she refused. Eventually, Ji Yu even forced Le Churan to go out with her. But when she graduated, Ji Yu felt guilty and decided to give the junior girl back her freedom by writing a long breakup letter, deleting her contact info, and going far away. Nowadays, nobody would believe it if Ji Yu said that she used to bully Le Churan around. When Ji Yu writes, a report, Le Churan says, "This doesn't make sense. Rewrite it." When Ji Yu glanced at someone else, Le Churan threatens her, "I can fire you for having an improper relationship at work." Gradually, their conversations became a little strange. "Kiss me and I'll write the report for you," Le Churan said with a serious expression. "Let's hold hands for an hour and you can have a day off tomorrow." "Come home with me... and I'll do anything you want me to."
