Ye Deva meri samajh se pare hai
Firstly, he almost confesses that he loves Tara, wants to clear all the misunderstandings between them... and then when he sees her with a guy, he just assumes that Deva has no place in her life.
Then he is grateful that she didn't hear anything but then he feels angry that she didn't hear anything ....
Tara didn't listen to the confession samajh me aata hai... coz she was at a distance from Deva and then she had those buds but why were they showing her expressions changing with every sentence he spoke
Deva is feeling sad that she didn't notice him in front of Arjun but she herself came and said that they couldn't speak even if she was infront of him that means she did notice him but at that moment her first priority was Arjun who travelled a long distance just for the medication of Tara's father... so I guess this was kind of justified ....
Khair, jo bhi ho really excited for the revengeful Deva
