Lia, an impoverished Omega girl living under someone else's roof, unexpectedly had a one-night encounter with Caesar, an Alpha from a top-tier conglomerate, while working part-time. After she became pregnant alone, her greedy mother and stepfather attempted to sell her to an old man for money. Desperate, Lia faced danger during a prenatal check-up but was saved by Caesar. Many misunderstandings arose between them as they spent time together. The malicious fiancée, Victoria, repeatedly plotted against Lia, even fabricating a paternity test to drive a wedge between them. Lia's family of origin also continued to exploit and oppress her.
Caesar gradually recognized Lia's resilience and kindness. He uncovered the truth of their one-night stand from that year, fully protected her and their child, and swept away all villainous obstacles. Lia overcame the inferiority and trauma caused by her family of origin. The two resolved all their estrangements, walked into marriage hand in hand, and built a stable and happy family of three. They healed each other, embarking on a mutually fulfilling journey towards a complete life.
