Prince Harry and Meghan Markle's joint royal engagement at the Endeavour Fund Awards last Thursday, March 5, was a successful comeback mostly due to one viral photo. Royal photographer Samir Hussein captured the image of the Sussex pair perfectly under the rain that royal fans said they look so happy, romantic and sexy.

According to Time, Hussein's shot of Prince Harry and Meghan, as they huddled under an umbrella on a rainy night in London, showed the couple glowing and smiling at each other. The captured moment seemed like a poster for a romantic comedy.

Hussein's photo lit up Twitter with many praising how it was beautifully and breathtakingly captured. Royal fans gushed over how Prince Harry and Meghan looked absolutely in love with each other.

The photographer said that it was a one in a million shot that had all the elements coming together perfectly -- timing, great lighting, an amazing subject and the symbolism. Needless to say, Hussein is extremely proud of the outcome of his photograph.

Royal correspondent Daniela Elser said that this one perfect won the PR war in the royal family. Elser wrote in News.Com.Au that it showed the Windsors what they are losing by kicking out Prince Harry and Meghan as senior royals.

Elser added that Prince Harry and Meghan's marriage did not just modernize the royal family. They also brought sexiness to it because they are two young, good-looking adults and that picture summed it up best.

Prince Harry and Meghan brought the "stardust quality" that the royals apparently lacked. Not even a photo of Prince William and Kate laughing as they played Gaelic sports in their recent Ireland trip could have such an impact.

Elser said that while Prince William and Kate are admired for their dependability and steadfastness, they do not have that exciting appeal that Prince Harry and Meghan exude. Thus, the Duke and Duchess of Sussex's resignation will be a big loss for the royal family, especially if they want to "sell" the idea of a monarchy to the next generation.

Meanwhile, at the Endeavour Fund Awards, Meghan was left teary eyed as she and the audience witnessed a veteran proposing to his girlfriend. Danny Holland popped the question to Lauren Price after he won the Recognizing Achievement award.

According to Daily Mail, the Duke and Duchess of Sussex spoke to the soon-to-be-married couple privately after the event. Prince Harry and Meghan congratulated the couple and said they were happy for them.

Prince Harry and Meghan were all smiles and kept with the PDA during the event. In her speech, the duchess said she was happy to be back amid an inspiring space.
