Sonshaun used there lack of trust and Lavanya's open display of love for Arnav at his advantage. But I can't completely blame it on him coz he just created situation and it was Arnav and Khushi who has to react accordingly. Even though there new relation was not something permitting yet there past friendship didn't allow the trust in each other is where they failed.
Had they acted maturely, communicating rather accusing other, trusting a little for friendship sake they won't have been in there current situation.
I'm assuming it's the last chapter of there past, but did Arnav find out Shaun's truth at all? Did he have any idea or does he know he was his competitor playing with his emotions for his reason to win over?
