Alhaitham came back from the Akademiya, he saw Kaveh, inside in the living room. He goes inside and waves at him. Kaveh knew... He was working for Azar, who had been being rude to him all the time, drowning him with work and trying to sabotage Kaveh's career. And indeed, yesterday, he lost his job.

“....” he doesn't talk

Alhaitham gulped and grabbed his hand. He explained some things that didn't understand but some made sense

“Wait.... What are you saying, Haitham? You knew this would happen...?”
