Good for them, they had great chemistry in mixed doubles, seemed to get along very well, so it makes sense. I know they were friends so why not take the next step, they're young, what do they have to lose?
People can look beyond the looks and fell for a person because of their nature and compatibility.
Looks are deceptive . Learnt it in hard way.
People who just go for looks suffer more because they don't see anything other than outer look of the particular person!
Oh yes...the chemistry they had during Hopman cup was so awesome...it was pretty obvious that Sakkari had a crush on Stef. Hope this relationship works...they are cute together. Maria is such a lively girl, looks like a fun partner to have ��
