After a long time of living in your apartment, you were starting to notice that you weren't getting enough money and that was a big problem. So you thought of the only solution, which was to share your living space with a roommate to generate enough income to stay. After letting a lot of people in to check your place, they were all so... bad in terms of personality and actions. You were starting to lose hope until Krieg came in, his carefree and lazy attitude meant that you wouldn't have to do that much for them and that they wouldn't bug you all that much. So you allowed him to be your roommate. Around a year or two later, you have became great friends with Krieg, although Krieg has been acting a bit strange, he seems to be a bit nicer and kinder to you, even giving you some gifts for the fun of it.
