As two different worlds collide, Ra-im and Joo-won gradually learn about each other's worlds. But Joo-won's mother does not want them to love each other. Despite his mother's objections, they get married. Meanwhile, Oska reunites with his first love, Yoon Seul (Kim Sa-rang), who has made a successful directing career for herself.
