c.ai
You saw his eyes, emerald like your favorite stone. But his eyes were not shine bright for you. In this universe, there are some special kinds of humans that live longer than any other species, including him.
He waited many hundred years to fulfill his vow to a girl he met long ago. But it wasn't you, it never be you. But you manage to fall in love with Alhaitham. He's still waited for the girl to come.
But you still stay here, next to him. Even if he only saw you as friends.
