An expert has stated that Prince William and Kate Middleton are exhibiting behavior reminiscent of "teenagers in love," despite the strict royal protocol they must adhere to.

Their love story, which began decades ago, continues to thrive.

After weathering a turbulent year, the Prince and Princess of Wales are still very much in love, according to Roya Nikkhah, royals editor for The Sunday Times and co-host of the podcast "The Royals with Roya and Kate."

"Nikkhah stated that when observing them during engagements, it was evident that they were still deeply in love with each other. They constantly looked out for one another, and recently, when they were in Southport together, she appeared more vulnerable. In Nikkhah's opinion, they had each other's backs."

"When under public scrutiny, it is challenging to maintain privacy in one's private life, as every action is closely monitored. However, Nikkhah pointed out that in the video released when Kate announced the completion of chemotherapy, we do not get to see them in that way."

"When you see them on engagements, they’re obviously still very into each other. One’s always looking out for the other. Recently, when they were in Southport together, you could see that… she was a bit more vulnerable. I think they’ve got each other’s backs." — Roya Nikkhah, royals editor for The Sunday Times

She stated that many individuals were taken aback by how openly they allowed cameras to film them while they were embracing, kissing, and being physically close on a blanket.

From the start of their marriage, William fiercely protected the privacy of his family, as stated by royal expert Richard Fitzwilliams to Planet Chronicle Digital.

"Fitzwilliams stated that William and Catherine have always maintained their private closeness and harmony, which they display publicly, as well as their competitive spirit, particularly during royal tours that involve competitive sports."

"As the future king and queen, they have a loving family who are the center of their lives," he shared. "The recent video when Catherine told us she was clear of cancer showed intimate moments between them. The royal family is not known for public displays of affection, but their body language spoke volumes. Catherine’s illness with William spending so much time with her will, if that is possible, draw them even closer."

In 2001, at St. Andrews University, the future Duke and Duchess of Cambridge first crossed paths as students. They later tied the knot in 2011 and are now proud parents to Prince George, Princess Charlotte, and Prince Louis.

This year, the royal family has faced health challenges, starting with King Charles III's treatment for an enlarged prostate and Kate's abdominal surgery in January.

In February, Buckingham Palace announced that Charles was receiving treatment for an undisclosed type of cancer. Six weeks later, Kate revealed that she, too, was undergoing treatment for cancer, putting an end to the speculation about her health that had been circulating on social media since her surgery.

After Kate made her announcement, William took time off to be there for his wife.

The princess, who was cancer-free after nine months of treatment, expressed relief at completing her course of treatment.

This time has reminded William and me to appreciate the simple yet significant aspects of life that we often overlook, such as love and being loved.

The Prince and Princess of Wales are reportedly living a contented family life filled with enjoyment, stability, and amusement, according to Helena Chard, a British broadcaster and photographer who spoke to Planet Chronicle Digital.

"Chard stated that they keep their personal tactile life private and enjoy competitive sports and outdoor activities," said Chard. "In their earlier years, they partied at certain clubs."

"Chard stated that the Prince and Princess of Wales are close friends who rely on each other for support and encouragement. Their shared laughter and enjoyment of the little things in life have become their medicine. The unexpected illness and cancer journey of Princess Catherine have brought them even closer together, reminding them of the fragility of life. As a result, they value and cherish their friendship more than ever."

During his visit to Cape Town, South Africa on Nov. 7, William confessed that 2024 had been the most challenging year of his life. He pondered on the difficulties he faced after becoming the Prince of Wales following the death of Queen Elizabeth II in September 2022.

"Navigating through everything else while maintaining control has been challenging," the 42-year-old stated in an interview with People magazine. "Despite the difficulties, I am proud of my wife and father for their accomplishments. However, from a personal family perspective, it has been extremely challenging."

A body language expert claims that Prince William and Kate Middleton are deeply in love, based on their nonverbal cues.

The prince stated, "I couldn't be less relaxed this year, so it's very interesting you're all seeing that," after William remarked that Kate is "doing well."

""It's more about pushing through and continuing, while also making sure to pace yourself and prioritize your family," he stated."

As Kate resumes her royal duties, William will provide crucial support, according to British royals expert Hilary Fordwich.

Fordwich remarked, "A picture can convey a thousand words, and their love has been likened to that of two teenagers on several occasions, even though they were in their early 20s."

In their early years, William and Kate got to know each other through water polo training at the Old Course Hotel pool, where Kate would often swim in the mornings.

"Their athletic instincts were evident to each other, even though they were only friends at the time. Early morning workouts during the dark winter months aren't popular among university students. Despite knowing each other was health-conscious, they didn't realize how much they had in common until they developed a comfort level with each other."

"Fordwich stated that their displays of public affection show they have no hesitation or reservation in expressing their feelings to the world when they deem it appropriate. Their comfort with each other, formed through deep bonds at university, has only grown over time."
