Spoiled by My Billionaire Baby Daddy

Yuna Lee is a college student with no money and tuition due. She swallows her pride and takes a deal that will pay it: one night with Sejun Han, the sole heir of a chaebol family under a curse of infertility that goes back generations. Sejun is cold toward her and holds a great deal of power. Later a doctor tells Yuna she is pregnant, with twins. Sejun, who was supposed to be unable to father a child, is stunned, and once he has taken it in he decides he wants the heir. He moves Yuna into the family mansion and gives her protection, money and comforts she has never had. The mansion turns out to be full of gossip and envy, and it is not a safe place for her.
