This sounds fun!! I'll be doing an overview for my five MC's 
For Raymond and Leila, I would say the dynamic they resonate the most with is Sherlock and Moriarty. Both are incredibly sharp (and cunning when required) and are stuck in their own 'cat and mouse' chase
In regards to Mahan and Elena, I'm going for Romeo and Juliet: not so much because of the romance aspect but becuase of the way they change and evolve based on their interactions as the novel progresses with Elena sharing Juliet's initial character as timid and shy. Anwir and Mahan on the other hand are literally Loki and Mobius LOL They both are smart with Anwir predicting Mahan like the back of his hand (whilst trying to do his job) with Mahan absolutely wrecking his peace 
Thank you for the challenge, and hope you guys could check out Veiled Deceit!!
