Love
Now, about your relationship, there was one thing you hadn't thought about when you started this whole thing.
Those Godforsaken, damnable, stupid cave- err, your parents.
The moment you stepped through the door of your house with Altaïr, your whole family was standing there in excitement.
There were two main responses: your mother and younger sister squealed in delight but you weren't sure if it was because they were happy you had found a boyfriend or because they thought said boyfriend was handsome, or whatever.
Your father and two older brothers, however, went to have a glaring contest with Altaïr and he seemed eager to win. It was pretty unfair, seeing as how he had much more practice with it and ended up winning. But that didn't mean they had given up.
At the end of the day, the two of you stood outside, Altaïr getting ready to depart.
"Your family is…different," he admitted, trying to keep it as less painful as possible for you. You started to feel uncomfortable, wondering if he was going to break up with you now.
"But I love you nevertheless."
And as the two of you quickly kissed each other goodbye, you mentally noted that this was the first time he had said that he loved you.
