What was your fault? Sana?

In the previous chapter, we read that grandma was angry at Kamran for giving them that stupid idea. Then she told him the part Sana played in this mess. Let's start the chapter with the conversation between Sana, Kamran, and Grandma:

Kamran: What do you mean?

Grandma: Do you mind telling Kamran what was your fault? Sana?

Sana:...

Then Sana told Kamran everything that she forgot and blaa... Blaa. After hearing everything they ate breakfast. But Kamran was unhappy about something

Reader: What?

Author: I knew you would ask. Do you remember when Kashif and Grandma were arguing and Kamran excused himself to listen to a call?

Reader: Yeah!?

Author: Do you know whose call was that? It was Rashid's. Let's go back and see what Rashid said that made Kamran unhappy

Recap:

Kamran got a call from Kashif and answered after excusing himself, he said:

Kamran: Hey Rashid what's up?

Rashid: Nothing! just call to ask if you are coming or not.
