Alright enough names but I dislike them together. I absolutely despise alliteration sets, especially among twins.
It seems like that naming trend for twins is quite common. It honestly just makes me shake my head.
I wouldn't say that
Roman & Rheo were too 'matchy' but the same starting letter and the fact they both consist of the same sound, doesn't help matter.
Roman &
Rhett for example would have been a tad less obnoxious.
Lastly, I don't like the spelling of Rheo at all.
Rio looks much nicer.
