Who are the most important characters in Owari no Seraph light novel?

After a delirious first night together, Shi Guang found herself waking up to a cruel reality… a breakup initiated by him, ending their relationship! What? Why? How? These were the questions that bugged Shi Guang’s mind in the two years after he left without a trace. Just as she thought that she had finally managed to get over him, Lu Yanchen suddenly appeared before her and before she knew it, she had to get married to this man who had dumped her two years ago?! What? Why? How? These were the questions that Shi Guang were faced with after his mysterious appearance once more. Just what are Young Master Lu’s motives? Why is he always watching out for her even though he was the one that had dumped her? And worst still… What’s with that tsundere attitude of his…?! Translator’s Review: This is a really sweet novel about a couple that just annoys one another in the cutest ways. Lu Yanchen is a descendant of a powerful aristocratic military family. Cold, aloof, genius and sharp, this is a man that has it all – status, smarts and looks. But none of that matters when it comes to affairs involving his silly woman as everything melts away into an encompassing warmth. Purple-Red Beauty is someone that spends a lot of time building the settings of her novels. Earlier on, I too was rather annoyed at some of the things that Lu Yanchen did. But once the story gets on track… everything suddenly seemed even sweeter than before! If any of you have heard of the Japanese manga Itazura na Kiss or have caught any of the many Japanese (Mischievous Kiss), Chinese (It Started With A Kiss) and Korean (Playful Kiss) drama reboots made for it, you will definitely love it! :P

"Missus, time to fulfil your duties!” Mu Yuchen demanded as he pulled Xi Xiaye closer with his arms intimately wrapped around her waist. — It was a meticulously planned feast for the powerful.

As she slipped away from her family that had turned their backs on her, she found him — Mu Yuchen, the low-profile and reserved noble that ruled City Z and led Glory World Corporation. “Mu Yuchen, let’s get married!” He looked up at her, then suddenly stood up. “Where are you going?” "Let’s go. Any later and the civil affairs bureau will be closed.”

Lin Xinlan, who possessed both spatial and wood manipulation abilities, was betrayed by her boyfriend and best friend. They had drugged her and sent her to a laboratory to become a test specimen all for the sake of a month’s worth of food supply. Having suffered both physical and mental torture, she chose to self-destruct, taking the lab researchers down with her! When she woke up again, she found herself in another era as a twelve-year-old girl named Lin Yuelan.When Lin Yuelan was nine years old, a Taoist who had been begging for water asserted that she would grow up to jinx her husband! Rumors spread and the assertion of her jinxing her husband turned into jinxing her parents, to her relatives, then her friends, and eventually she was said to be a jinx of the world. Her grandparents, uncles, and awful relatives were terrified of being jinxed to death, so they resolutely severed ties with nine-year-old Lin Yuelan. They removed her from the family register and made her live on her own. Her foolish father had obeyed the clan’s wishes, her mother was a crying mess, and her siblings couldn’t do anything to help. Being separated from the family at nine years old, she was given a shabby and shaky little hut, one paddy field, and two dry fields as severance compensation. From then on, the Lin family had nothing to do with Lin Yuelan, and Lin Yuelan became a girl with no background. She warily reached the age of twelve, but accidentally offended the village’s bully. The bully’s comrade eventually beat her to death, and that allowed Lin Xinlan to transmigrate onto her.“I have spatial abilities, and the world will be mine! Watch as I, Lin Xinlan, command authority wherever I go, and become a supreme being!”

In her pursuit of saving enough money to return home, Hannah found herself playing the role of the "first-love" character in a beloved novel. Originally, this character was a typical stand-in supporting actress, taking on various substitutes for the female lead as dictated by the male protagonists, such as donating kidneys or sparing road for the female lead, which she all agreed. Eventually, the original character succumbed to the pressure, turning dark and meeting a tragic demise with a disfigured face on the streets after being killed by the male protagonists. Hannah's task was to follow this grim plotline and achieve the tragic story's intended outcome. However, in the eyes of George River, she was merely a substitute he had enlisted—an entity dependent on him. When his true love returned, he callously abandoned the woman who deeply loved him. Later, he regretted his decision, only to discover that the once-begging woman was now surrounded by various exceptional men. The individuals who had previously used her as a shield—the movie king, the ambitious young actor who climbed over her for his ideal goddess, and the president who regretted his actions upon regaining his memory—all found themselves humbly pleading for her affection: "Hannah, the one I love is you." Confused by the sudden turn of events, Hannah observed her bank account steadily growing and stumbled upon a newfound skill for crafting tragic stories. As the main antagonist who successfully survived until the end of the story, Arnold Simmons was ruthless, dark, and violent. In his eyes, Hannah appeared to be the most naive woman he had ever encountered, her thoughts consumed solely by love. Witnessing her continuous deception by those around her, Arnold eventually reached a breaking point and seized her, declaring, "Stay by my side; let me handle your tasks."
