Wait, this is Japanese? That is so cool! I love almost all Japanese names because they are so cute (Emiko, Fumiko, Miyoko, Sakura, etc.), but this is so adorable! At first I thought this was a variant of Raina :P.
Hi, my name is Reina and I’m Mexican. I never knew my name would be used for different things and meanings. I also never met someone who spells their name like mine but I know there are many out there. So I just want to say yes, some people might say your name wrong at first but once they get used to it they’ll learn to love it.
In Yandere Simulator there is a teacher called Reina Nana. -But on another note, I love the name. Not only is the spelling cute, but it can also be used in different cultures and can't be considered weird. A lot of Japanese names have comments like, "I would never use this name outside of Japan", but this name is obviously the exception and is incredibly adorable.
