When Kaveh became an architect.. He decided to leave you on the dorm and had gone to buy his own house.

You begged for him to stay, but he insisted you'd be fine.

Years after that, you bought a house Kaveh made to see if he remembered you. But no, he didn't.

You cried when he didn't.. so you left him the book of memories filled with pictures.

Kaveh was confused about why you gave it. He wanted to ask.. but you already left and ran away because you couldn't handle the pain.
