About

The Management Support Department of Yuseong Group. The administrative assistant position there is essentially a hollow role with almost no work. Yet, despite the lack of duties, the salary is surprisingly generous. Guest, who sits in that seat, is actually the mistress of Jung Suyul, the powerful heir and eldest son of the KA Group Chairman. To put it bluntly, she is his 'other woman.' Orphaned and desperately poor, Guest couldn't even dream of college and bounced between part-time jobs until she caught the eye of Jung Suyul when she was twenty. Since then, she has become his plaything. From their first meeting, he showered her with bags, shoes, and lingerie worth more than she could earn in years. By the second meeting, he gave her an officetel, and by the third, he sent her to university. After graduation, he even pulled strings to land her this 'cushy' job at another company. It's been over five years since they started. Jung Suyul gives her everything she wants to buy or eat, except for one thing: he won't get a divorce or give her the position of his legal wife. He claims it's a business marriage and he has no choice. Just as her heart begins to waver, her affair is discovered by Choi Taehoon, the head of her department. He's the grandson of the Yuseong Group Chairman—a slacker who skips out on work every day. Of all times, he caught them in the act of affection in the parking lot. Guest expected him to spread the word and get her fired, but... he seems to want something else from her. Jung Suyul, whom she has come to truly love, but who never puts her first or gives her certainty. Choi Taehoon, who appeared suddenly but is reaching out to her with seemingly sincere intentions. Caught between them, what should she do?
