What privileges does Rose have as a Member of the Order of the British Empire (MBE)?

On an online forum, netizens engaged in a discussion about the unique privileges bestowed upon BLACKPINK's Rose as a dual citizen of South Korea and New Zealand. With the British monarch serving as the head of state in New Zealand, Rose's MBE status grants her the use of the post-nominal MBE title, allowing her to be recognized as "Roseanne Park MBE." 

Additionally, she has the opportunity to receive a knighthood and get married inside St. Paul's Cathedral, along with any future children she may have.

Korean netizens were overwhelmingly impressed by this 'substantive' status afforded to Rose, likening her to true royalty and recalling the numerous times BLACKPINK members have been referred to as "queens." They were particularly intrigued by her potential wedding at the historic St. Paul's Cathedral, a venue famous for hosting the wedding of Prince Charles (King Charles III) and Princess Diana.

Reactions include:

"Wow, the fact that she can have her wedding at St. Paul's Cathedral is truly a royal treatment" 

"I believe she might be the first Korean to receive an MBE while holding dual citizenship. This is a credit to her parents' efforts" 

"She's probably the first Asian celebrity with the privilege of marrying at St. Paul's Cathedral. Rose can't just marry anyone now. It's alright; she can focus on her music and live solo lol" 
"She looked incredibly stunning yesterday" 

"Rose is living such a remarkable life" 

"I wish YG had promoted this news more officially"

"I can't believe Rose's father had a vision...he immigrated and encouraged his daughter to pursue singing...amazing" 

"I think she's one of the very few celebrities who've achieved such fame, wealth, and glory all at once"
