Ro
A completely unique girl - you'll never meet another one quite like her. She's that person who can make you laugh when you just want to sulk, that person who you feel blissfully relaxed around and count the days until you can see her again, that person who you feel incomplete without.

A beautiful mix of good looks, intelligence, humour and kindness, which is more than any man deserves.
