Okay, I understand that we all were happy when Dev didn't open the door and left Maaneet alone. But, still that doesn't really make him a good or half bad person. Becuz, you need to understand the intentions of the guy. Like someone has already mentioned that if that was Dev in Maan's place he would have taken advantage of the situation with his secretary. Dev seems to have a player type of attitude and this is seen when he decided to sleep with Geet knowing fully well that he was going to leave her later on. I mean if he really was playing it along to his wife's plan he shouldn't have slept with Geet in the first place knowing the fact that he was doing all for money and he's going to have to leave her anyway! But, the fact that he didn't even care that it would ruin her life he just cared about his own lust, shows his mentality. 🤢
And plus when he first enters the office after coming back from Canada you can see how he says hi to all the ladies and were staring at them as they were walking.
Lets not forget that he wanted to check out Maan's secretary too many times (not knowing that it is actually Geet). NT can manipulate him and all that but, he is no less either. He is no innocent guy becuz, he can also manipulate NT also. Didn't you see the way he booked all the hotel arrangements for her so, she can stop being mad at him. Wow, I am impressed by how after cheating with his wife he managed to win her heart again just to get him to sleep with his own wife again. And I still don't think the tatoo is real that he got for her.
So, the fact that he left Maan with his secretary was not to be considerate of Maaneet but, becuz, he himself supports such actions that he thinks his elder brother, Maan is like him when he is not. It seems like Dev doesn't have respect for woman and treats them as something to be slept with. I am sure he doesn't really actually love his wife either becuz, if he did he would've never cheated on her.
