First of all i just now talked to hemadi and changed my mind completely...
See dev did the right thing today...now pplease don't bash me for thisđ
but just think if dev would hv agreed to marry kajal to save his own life,i m sure we would hv bashed him by calling him selfish.
but for dev kajal's life was more important,and he had no other option,i mean if he would hv told kajal that go and get married to dhruv because i will die in few days,i m sure kajal wouldn't hv agreed,so he thought that theres only one way out and that is to somehow make kajal hate her.
so then he came up with this plan to misbehave with her in a hotel room so that she starts hating him and agrees to marry dhruv,but while doing this even he would hv felt the same pain in his heartđ...common just imagine a guy who loves this girl more than his own life is doing this thing just to save her from the cluthes of death,isn't that commendable...i know we may say that kajal's reputation may affect due to all this but then dev is thinking "i m going to die in few days,and i don't want kajal to cry for me,so its better she starts hating me; and reputation and all can b rectified, if life is there because there is nothing beyond life".
all in all dev wants to see kajal's secure future,which he thinks is possible only with dhruv,but little does he know that destiny has other plans for himđ..so basically dev is not stooping himself low but he is making himself inferior in front of kajal so that he thinks even if i die,kajal won't remember međbecause of what i did to her...
