The pros

Appearances are deceiving as far as Chloe and Yannis are concerned: they’re actually very idealistic about love.
They won’t settle for second best and they’re absolutely terrified of getting stuck in a rut. They only spend quality time with each other, and this way they avoid the usual quibbles and arguments of day-to-day life.  

They respect each other’s privacy, and their personalities each develop in different ways as they grow older. Chloe has totally different interests and hobbies to Pete, so they really enrich each other. They’re very independent and if they were to break up it wouldn’t be a great shock.

Their honesty and openness in all they do means that infidelity is out of the question.
