Yes, when Manik started to threaten Aryamaan with two glass pieces (personally I am very very happy), Nandini came and rescued him. After that Nandini told Manik that due to anger, he may put himself in big trouble and that time even Nandini won't able to save him. Very true, Manik's anger is out of control. And especially if someone will want to hurt Nandini, he will burn entire world. If from anywhere, he will come to know about Aryamaan truth, he won't spare him. Again Aryamaan may target Nandini to hurt Manik as Nyonika and Harshad may manipulate him that Nandini is responsible for everything. Manik will suspect Aryamaan for everything now. Just hope he won't repeat the mistake during Soha for which Nyonika may take advantage of it.
Another dialogue of Manik to Nandini that due to this hiding you will land yourself into trouble. Aisa na ho ki mujhe pata na Chale. Very very true. Nandini hiding issue is bringing a storm, I can say this time it will put toughest exam in front of manan to protect their love. They will face pain. Because Aryamaan jerk is under revenge mode and he is believing wrong people. They can mend him in their own way. This is highly necessary that Nandini should share things with Manik. This will give strength to their relationship.
Third dialogue that Manik please leave, otherwise we will both hurt. So true, one's anger and other's hiding or I can fight alone attitude will put both of them into trouble.
They should do everything together now. As if Nandini said to Nyonika that they can handle anything as long as they are together. This time cvs should manan togetherness instead of individual fighting to protect their love.
