Secretly Pregnant with the Billionaire's Daughter

Six years ago, college student Isabel was framed, leading to an unexpected encounter with billionaire heir Ethan, after which she became pregnant and dropped out of school. Six years later, Isabel works tirelessly to raise her child, who suffers from severe allergies. By a twist of fate, she joins Ethan's company and becomes his personal assistant.

Faced with relentless bullying and even life-threatening schemes against her child by the vicious heiress Rachel, Isabel refuses to back down and bravely fights back. As they spend time together day and night, Ethan not only repeatedly steps in to save her but also falls deeply in love with her. As the plot unfolds, the child's true bloodline identity is unexpectedly revealed to Ethan's family, specifically his great-grandmother, Olivia.

In the end, the malicious Rachel faces the consequences of her actions and is handed over to the police. Isabel unexpectedly becomes pregnant with twins—a boy and a girl—and shares a grand, perfectly happy ending with Ethan.
