Story Recap
Episode 1
Yuna Lee's life is already falling apart when the news lands: she's pregnant. A scan shows two babies—a twin pregnancy. Twins. But the scene that opens this drama isn't joy—it's desperation. Yuna is scraping together tuition money, checking her balance, and discovering she's down to her last scraps while her mother insists college is a waste of time. "Your younger brother comes first," her mother says. The family dynamic is brutal: Yuna's education matters less than her brother's needs. Then comes the offer—one night with Sejun Han for money. Yuna's face says everything: how far will she go to escape?

Episode 2
The deal is laid out bluntly: one night with Sejun Han, and she'll get more money than she's ever seen. Yuna hesitates, but tuition is due and her mother's pressure hasn't let up. "Just one night, right?" The terms are confirmed: one night only. Sejun's world is cold and transactional—his mother is already pushing him toward arranged meetings, frustrated by the family's long struggle with infertility. Yuna goes through with it for the registration fee. But the aftermath hits differently: alone, she whispers the fear that will define the rest of the story—"How will I raise two children by myself?" She doesn't know yet that Sejun will soon learn the truth.

Episode 3
One month later, the secret is out. Sejun hears the words that stop him cold: "The girl you slept with a month ago is pregnant. Even twins." His mother reacts with shock, revealing the family's painful history—generations of infertility, her own surprise at twenty-two. For a chaebol family that has struggled to conceive, twins are almost impossible. Sejun is ordered to find Yuna and help her, no matter what. But when he does, Yuna pushes back hard. She doesn't want his charity or his family's interference. "You have no right," she says. The power imbalance is stark: he has money, name, and a family legacy to protect. She has nothing but her pride and two unborn babies.

Episode 4
Sejun makes his move—and it's not romantic. He offers to cover Yuna's tuition, but the conversation curdles fast. "So money was the goal all along," someone accuses. Yuna's mother sees dollar signs: if Yuna gives birth, the Han family will pay handsomely. The stance is chillingly practical: "If you just give birth to the babies, we can take them." Yuna is horrified. She's not a surrogate, not a transaction. But with no money, no support, and her mother pushing her toward the Han family's wealth, she's trapped between two ruthless forces. The question hangs heavy: is Sejun offering protection, or just claiming what he believes is his?
Episode 5
The truth about Sejun's identity explodes. Yuna's mother realizes exactly who he is—the heir to Haize Group, a man with connections reaching into industry and government. "That man got you pregnant?" The family's interest shifts from shame to strategy. Meanwhile, Sejun acts: a transfer of 2.5 million won lands in Yuna's account, covering her tuition. It's a message—he's watching, he's involved, and he's not going anywhere. But Yuna's mother is already scheming about how much the Yeongga side will pay. Yuna stands at the center of a tug-of-war between a mother who sees her as a payday and a billionaire who sees her as the mother of his heirs.
Watch how Yuna fights to keep her own voice when everyone around her has a price in mind.
