Lilia unexpectedly became pregnant. Misled by false documents fabricated by the villain, she mistakenly believed Dominic intended to get rid of the child, and fled into the rainy night. Dominic uncovered the entire truth and had a sudden realization. He desperately stopped the fleeing Lilia, casting aside his pride to genuinely repent. The two resolved their numerous misunderstandings, worked together to eliminate their enemies, and after enduring many hardships, ultimately held a grand belated wedding, welcoming a perfectly happy ending.
