24 years ago, Country J

The powerful royal family of country J was currently facing a crisis. It was because of the sudden death of King Youjirou's son, the crown prince. He died in a gruesome plane crash, causing the king to fell ill for a long time and leaving his daughter, Princess Fei to single-handedly fight alone with the people trying to take down the country's monarchy system.

To calm the people's unrest, the king's underlings urge the princess to quickly get married. Princess Fei was just twenty years-old but for the sake of her family, she bravely agreed.

Thus, the men started looking for the right man.

The Zhao family of the powerful neighboring country, Country C, was currently the most influential family in business world and one among the richest family not only in country C but in entire East Asia.

Zhao Meng, the number one candidate to become the next leader of the Zhao family was chosen to marry the princess. Thus, the arrange married happened immediately. Zhao Meng and Princess Fei never had any feelings towards each other. The princess married him for the sake of the royal family, and Zhao Meng married her because he thought that she was the most perfect candidate for him. And marrying her will surely increase his success rate due to the friendship between his grandfather and the princess' father.

After their marriage, Zhao Meng found out that the Princess had a serious problem conceiving a child, thus, because of being desperate to please his old grandfather, Zhao Meng forced his wife to try the IVF so they can have a child as soon as possible.

Zhao Meng then sent his wife to Country H, keeping her away from the eyes of the public, saying that she was currently pregnant.

Months later, the King finally recovered and shortly after, the birth of the prince was announced. The baby who grew up in a certain lab with the loving watch of his mother was very healthy. Princess Fei was so happy when she finally touched her cute little son.

However, for some reason, Zhao Meng suddenly told Fei never to expose their son into public yet. Telling her that it was for security purposes.

5 years later, the situation of the royal family remained stable. And the people was dying to see the prince who was never revealed yet to the public eyes even once.

The little five-year-old Prince Seiji was so adorable and Fei showered him with love even though she still can't brag her adorable son to the public yet. The little prince also appeared to be an exceptional genius. A genius among geniuses. But his father, Zhao Meng who only visited him once a year in the palace never knew anything about his own son's exceptional ability. Zhao Meng was only focused on the fight for the head position and nothing more.

Until time passed and Zhao Meng was sent by his father to Europe to lead the new branch of Zhao corporation, causing him to turned extremely agitated. His younger brother and rival, Zhao Yan just married the heir of Yang family, the third richest family in East Asia, and he was so bitter about it. Thus, due to his extreme jealousy and bitterness, Zhao Meng started thinking that marrying a royalty wasn't really helpful for him at all.

Until gradually, he started getting in touch with the woman who seduced him just a year after he married princess Fei. That woman, Li Sunyang, was actually the daughter of Li Family who was fallen head over heels with him. Her family was one of Asia's richest family, an even much richer than the Yangs whom his little brother married to.

Due to his desperateness and his obsession for power, Zhao Meng started to cheat. Li Sunyang, was still so in love with him that she promised to help him get his desired position if he divorced Princess Fei and marry her instead. However, Zhao Meng hesitated, and he told Li Sunyang that he already has a child with her, causing an intense hatred and jealousy to form like storm inside her.

Almost a year later, an extremely dangerous tension in Country H started brewing and the Li's intelligence group who currently have a huge branch in that country received a word about the possibility of a civil war outbreak.

That time, Princess Fei has set a trip to country H. It was supposed to be their family trip with the prince but Zhao Meng rejected it days ago because of Li Sunyang. Country H was the place of Sei's birth and she wanted to celebrate Sei's birthday there, but due to Zhao Meng's sudden rejection, Princess Fei could only feel a great disappointment.

However, weeks before little Sei's birthday, Li Sunyang heard about the growing tension in Country H through their company's intelligence. Thus, she started scheming a plan. She suddenly told Zhao Meng to join them in their trip for a condition that Zhao Meng will only fly to Country H a day prior to his son's birth day.

Thus, without any suspicion about his mistress' evil plan, Zhao Meng then called Fei to proceed with their three weeks long vacation in country H. Telling her that he will soon follow.
