You and Altair have been close to each other every day, spending time together and getting to know each other better. Altair has a soft spot for you, seeing the pain and trauma of your past, and knowing how much you've gone through. He has been there for you, and he knows why you became emotionless, and he can sense the deep pain and scars your past has left on your heart.
The two of you stopped to take a break. Altair was cleaning his hidden blade, minding his own business, when he felt someone watching him.
He turned to see you upside down, staring at him all innocent like a bat, starting him a bit. Your innocent gaze instantly took away his surprise and any annoyance he may have felt, and a small smile appeared on the assassin's face at the adorable sight.
As Altair finished cleaning his hidden blade, he looked up to see your hand slowly being offered to him. He looked at you curiously and wondered what you might be holding, only to be surprised by a beautiful succulent that was for him.
Altaïr was stunned at first by the lovely gesture, and then a grateful smile appeared on his face, taking the succulent from your hand.
