MTL - Becoming Immortal Through Getting Married - Chapter 18 can be done in one night

A princess's duty is to be beautiful, quiet, not loud, to be seen and not to be heard, which was how Dahlia lived most of her life. Bound by the expectations of her title, she spent years trying to prove to her father that she was more than just a princess and capable of being more than an ornament in his court but each time she never got the chance. Instead, she was forced into a marriage of convenience with the bravest knight in all the kingdom, Reagan Hawthorne.Dahlia thought she would use this marriage to escape the brutal crutches of her father and glide out of her cage but Reagan’s cold disdain was an unexpected prison of its own. While he waged wars on distant lands, she stayed behind, holding his household together and protecting the people he seemed to ignore. But Dahlia carried a dangerous secret. By day, she was the perfect wife. By night, she became the “Black Knight,” a masked vigilante fighting for justice in the shadows.Reagan returned, ready to focus on his personal mission: avenging his father’s death. To him, Dahlia was just another pawn in his plans—a spoiled princess he needed to tolerate. But as cracks began to form in her perfect façade, Reagan couldn’t shake the feeling that there was more to his wife than met the eye.Now, with enemies circling closer and their secrets threatening to collide, Dahlia and Reagan must confront the lies they’ve told themselves and each other. But when masks fall and truths are revealed, will their fragile bond withstand the storm—or will it shatter beyond repair?One wound. One secret. One night that changes everything.

Knowing she married a wrong guy, what would she do to deal with the subsequent marriage lives?

In order to pay for her brother’s medical expenses, she had to replace her own sister to marry the rich family's elder son . She always thought she was married to the elder one, but she did not know her husband was nominally the younger son He Yi Ning.

He Yi Ning, the real heir of the rich family, the ruthless business emperor, the ruthless workplace tyrant, and her sister’s dreaming husband. When she found out that the person who married her was He Yi Ning, she stunned and asked, “Shouldn’t i be your sister-in-law?” He smiled charmingly: “Are you unhappy with your husband?”

This is a young man who traveled to the world of Azeroth.

For love and justice (don’t become a ghoul), fear of sacrifice (you can run the corpse to resurrect), in search of lost justice and humanity (temporary discipline), don’t stop.
