I saw the confusion in cheel n naag. But I believe Veer is cheel only and jay is naag
But like season 3 jay will be after manhoos naag Mani (like every season) n Bani's real love will be veer.
In every season they show forbidden love story of naagin n human but this time it's naagin n cheel.
Vrinda asked naageshwari that why aakesh's love was bad to which she replied he knew she already had a pair.
So if her naag is bad than her true love is cheel.
Also positive side of veer hints the same
