原Lol I like my name I guess, it's pretty cool. It's weird though because I live in 'Merica and I always have to explain that it's pronounced like 'arena' and not 'ee-rena' haha, but other than that it's a nice name to have.
原My name is also Arina. But I'm from Germany, not from Russia, Ukraine, Hungary or something like that. :) Here in Germany almost nobody knows or has this name, at least I know nobody. But I like it and I have it because my father is from Belgium and it's also very popular there.
原This is my friend's name. She's from Ukraine but we live in the US. Written down it looks pretty, but its kind of funny to say if you say it like the word arena. I say it more like ear-eena. It's a pretty name, but I'd suggest using it only if you're of Russian descent. Otherwise it looks kind of a like a "creative" name.
