Was Kamran worried for Kashif?

In the previous chapter, we read that Kashif was rushed to the hospital and then his colleague brought him straight to Sana's house in the evening. Then his colleague left the hospital, and right at that time Kamran arrived, he saw Kashif's colleague but did his colleague see him? Both of them saw each other but both of them were unaware of themselves. By the way, he was worried to see someone leaving Sana's house but he ignored it and waited for Kashif as it was time for him to come. After waiting for a long time he was worried, and he decided to check on Sana as he was suspicious about the man. So he went to Sana's house, he knocked and the door was opened by Sana. As Kashif was in her room so he didn't see him and the conversation started casually:

Sana: What are you doing here?

Kamran: I am here to ask a question⁉

Sana: What?

Kamran: Who was he?

Sana: Who?

Kamran: I saw someone leaving your house a while ago

Sana: him! he is Kashif's colleague
