Chloe and Yannis' formula

Chloe and Yannis also have a strange understanding of the laws of mathematics:  
1 + 1 =  1 + 1 (you + me = you + me).

They’re madly in love, but not necessarily with each other – they’re in love with their freedom, and they guard it fiercely.  

The reality
Chloe and Yannis are two individuals and they’re very careful about respecting their differences: there’s nothing they fear more than losing their identities in a fusion relationship.  

Their independce doesn’t threaten their love for each other, but it does threaten their life à deux.
