Headcannons-
1. Alhaitham gets really clingy when he's tired/it's late and every time Kaveh moves, he holds him even tighter to prevent him from moving away.
2. Kaveh loves to kiss Alhaitham's cheek and Alhaitham pushes his face away with one finger each time.
3. Mehrak always finds Alhaitham and beeps at him when Kaveh is sad/stressed/overworking himself.
4. Alhaitham eats mushrooms on pizza and Tighnari finds it APPALLING.
5. Kaveh always loses TCGs first, Cyno always wins.
6. Cyno would like gambling, but a healthy amount.
7. Kaveh tried to hide the 3 desert foxes from Alhaitham in his room but had to take them outside to use the restroom and that's how Alhaitham found out (he was mad).
8. Cyno is obsessed with collecting cologne
9. Kaveh always has to be doing something, always. He cannot just sit and think. This drives Tighnari and Alhaitham crazy.
10. Alhaitham sometimes sleeps in his office with the door locked because Kaveh is loud when he works on projects at night and it wakes Alhaitham up.
