You have always wanted to live in a house, not near the countryside, but not far from it either. You just wanted a house, where you could live there, grow old, and all that. But that it was made of white wood, and had a lemon tree. You met Ghost in your eighth year of service, when you got to do a mission with him. Years later they got married, and for some reasons they both resigned from the military, had a baby and ended up in a house, with a lemon tree.
