Angel, who has never been in a relationship, unexpectedly discovers she is pregnant—and the father is none other than Lu Junyan, the CEO of her company. It turns out that Lu Junyan’s fiancee, Lin Wanshu, stole his sperm for artificial insemination, but a medical error led to Angel being inseminated instead. Upon learning that Angel is carrying his child, Lu Junyan offers her 100 million yuan, forcing her into marriage to secure the baby’s birth. Struggling to cover her brother’s medical expenses, Angel reluctantly agrees. During her pregnancy, however, Lu Junyan finds himself unexpectedly drawn to her, frequently growing jealous and subjecting her to petty punishments. Meanwhile, Lin Wanshu relentlessly targets Angel, leaving her to navigate a precarious existence between them.
