Apologies for grandma!?

In the previous chapter, we read that Kashif after doing breakfast got up to leave and went to the doors Sana followed her and stopped him, while grandma continued her breakfast because of Sana's words, Sana on the other hand stopped Kashif and said:

Sana: Wait Kashif!

Kashif: What is this behavior, Sana? first, invite me for breakfast and tell me that you want to talk about something important and when I ask you about it you ignored me

Sana: I know I was being strange ragnaroad you I am sorry about as I just invited you to apologize for my grandma

Kashif: Apologies for grandma!? For what?

Sana: For her condition that she had put for our wedding

Kashif: Don't overthink Sana I am not upset or angry about her condition I know that she needs some security for you and it is her right she is an elder we need to respect her decision and from your accent, I will believe that you have been upset from your grandma since you have sent a message to me, Isn't it?
